NRMCA e-news

NRMCA's celebration of the 100th anniversary of ready mixed concrete in the U.S. continues in April with the histories of another Producer and Associate member. See below for the two companies we've selected for this week, along with a link to that company's respective Web site for more information. This week's industry milestone: By the time construction of the Pentagon was complete in 1943, 1,492 concrete pilings were driven and 410,000 cubic yards of concrete went into the building, using 680,000 tons of sand and gravel dredged from the adjacent Potomac River.

Ratliff Ready Mix - This Waco, TX-based Producer member is a construction materials supply company, specializing in ready mixed concrete and construction aggregates.

Corn stover, wheat straw and rice straw are waste products of agriculture used as biofuels. The high-lignin ash left over from burning them is being used by researchers at Kansas State University to make concrete stronger and more eco-friendly. The researchers use the byproduct to replace 20% of the portland cement by mass and in doing so make the cement 32% stronger.

Researchers from Michigan State University (MSU) and Wayne State University are applying to the federal Small Business Innovation Research program this year to fund their different approaches to maintaining roads and bridges. Shantanu Chakrabartty, an associate professor of electrical and computer engineering at MSU, has been working more than seven years on a method of gathering data from wireless sensors on a structure that is subject to weight load, friction and pressure forces, like a bridge or highway. 

Hwai-Chung Wu, associate professor at Wayne State and president of startup Reinforcement Innovations LLC, said his company incorporated last year out of more recent research that is evolving quickly. Testing about 18 months ago showed promising results on concrete columns that use a hybrid composite reinforcement instead of traditional steel reinforcements, he said -- the concrete didn't crack or speckle like steel-reinforced columns often do, and didn't compress as much.

The Canadian province of Ontario’s concrete industry has been enjoying the benefits of the province’s efforts to construct more wind energy and turbines. Concrete has been the material of choice to use as the foundation for wind towers, according the NextEra Energy, one of the largest wind and solar energy developers in North America. "Given its durability, resilience and continuously improving environmental footprint, concrete can play an important role in building sustainable infrastructure," said the Cement Association of Canada in a statement to the Daily Commercial News.

Some of Honolulu's busiest roadways are under major reconstruction. Faced with deteriorating asphalt at some bus stops, local officials have decided to use concrete for longer lasting repairs.

NRMCA industry partners in Minnesota recently held three parking lot overlay seminars in three different cities in three days, reports Senior National Resource Director Jon Hansen. Working with Doug Burns and April Stier of the Portland Cement Association's North Central Regional Office, the first two seminars were held in Eden Prairie and Albert Lea. Both seminars were well attended with over 25 people attending each presentation. The audience mix represented contractors, municipal, large business owners and NRMCA National Account clients. The 3-hour seminars focused on pavement rehabilitation with concrete overlays and the sustainable benefits of paving with concrete. 

The third seminar was hosted by NRMCA Producer member Cemstone and was held in Mendota Heights. The morning-long session included Hansen speaking on the newly released Guide to Concrete Overlays of Asphalt Parking Lots and sharing examples of successful parking lot overlays around the nation. Also on the morning program was a contractor from Wisconsin who recently purchased a laser guided screed and shared his experience on selling and delivering concrete parking lot overlays as a rehabilitation option to owners. Rounding out the morning program, a representative from an equipment company talked about the process of constructing successful overlay projects using a laser guided screed.

The 2013 Professors Workshop, co-sponsored by NRMCA and organized by the Portland Cement Association (PCA) is designed to provide faculty in engineering, architecture, and construction management programs the tools to teach the latest developments in concrete design, construction, materials, pavements and sustainability. The week-long event, scheduled for July 15-19 at PCA’s Skokie, IL, campus, includes networking opportunities to facilitate the exchange of ideas with professors from many universities. Four comprehensive sessions include:

• Concrete Materials and Properties

• Engineering and Economics of Reinforced Concrete Buildings

• Design, Construction, and Performance of Concrete Pavements

• Design and Construction of Concrete Bridges by the AASHTO LRFD

This informative workshop provides a forum that enables professors to take full advantage of all the resources available for each subject as it pertains to their curriculum. Industry groups are encouraged to identify professors interested in attending the workshop and sponsor their attendance by reimbursing registration fees and travel expenses.

Evolving from its Regional Work Plan Meetings held annually across the country, NRMCA is adding an educational component to its already successful formula of coming together with staff and member leaders of state and area associations, Portland Cement Association, American Concrete Pavement Association and other interested parties to share information about critical industry trends, available tools and resources and new initiatives being developed to make concrete THE construction material of choice.

The first of these new Regional ConcreteWorks events, for the Lower Atlantic Region, is scheduled for Monday, May 13, in Frankfort, KY, at the offices of affiliate partner Kentucky Ready-Mixed Concrete Association. The agenda will include sessions on Architecture 2030’s Challenge for Products, Building with Resilience in Construction and will also have an opportunity for each affiliate organization in the region to highlight critical issues impacting the concrete industry in his/her state, as well as provide information on initiatives underway that provide resources and tools that may be useful to share with other states. A small fee is being charged to cover the lunch which will be served during this 11:30 a.m. – 3:30 p.m. meeting. Interested parties in the Lower Atlantic (or neighboring) regions are welcome, but space is limited to 40 and will be held on a first-come, first-served basis.

The preliminary estimate of ready mixed concrete produced in February 2013 is 17.5 million cubic yards, 0.7% higher than February 2012. The production for the first two months of 2013 is estimated to be 35.1 million cubic yards, 3% higher than during the same period in 2012.

The ACI Spring Convention in Minneapolis was held last week. NRMCA staff attended and provides the following updates of some of activities that involved NRMCA representation.

130 – Sustainability Committee - The committee continues to struggle to publish a comprehensive guide on concrete sustainability. The large scope of the document, size of the committee, special interests and rapid movement of the green building movement are hampering the development of this document. NRMCA worked to develop chapters on materials, production and construction, each of which have been balloted and finalized. NRMCA will continue to work on the committee to ballot other chapters of the document. Lionel Lemay maintains representation on this committee.

132 – Responsibilities in Concrete Construction - The committee is in the final stages of completing its document on responsibilities in concrete construction that will be submitted through the ACI review process for approval. The committee discussed and assigned a task group for developing a document on responsibility on installation and testing of floor coverings on concrete slabs. The committee sponsored a Hot Topic Session on responsibility that included very interesting presentations from Jeff Coleman (Coleman Law Firm) who discussed the history of the development of the committee’s document, Julie Buffenbarger (Lafarge) on litigation associated with LEED projects, Casimir Bognacki on performance specifications implemented by this owner and the implications to responsibility (Port Authority NY/NJ), Kevin MacDonald (Beton Consulting) on the responsibility of mixture proportioning from the concrete suppliers' perspective and from Boyd Clark (CTLGroup) on forensic investigations and consulting services. Colin Lobo maintains representation on ACI 132.

201 – Durability - The 201.2R Guide to Durable Concrete is being revised. Chapters on Corrosion and Abrasion Resistance have been revised. Abrasion chapter includes discussion on pervious concrete. Karthik Obla maintains representation on ACI 201.

211 – Mixture Proportioning - The document Standard Practice for Selecting Proportions for Normal, Heavyweight, and Mass Concrete is being re-balloted. Comments from the ACI staff engineer on the new chapter on concrete mixture submittals have been addressed by the committee. This chapter includes examples of prescriptive and performance submittals. New task groups are working on mixture proportioning for pumping and mixture proportioning with ground limestone powder and mineral fillers which will be handled in separate sections. Karthik Obla maintains representation on ACI 211.  

214 – Strength Tests - This committee is looking for project compressive strength test data to update the table showing the standards of concrete control for both testing variability as well as batch to batch variability. Karthik Obla is as an associate member and has been helping to collect strength test data from members.

232 – Fly Ash and Natural Pozzolans - The committee resolved most of the negatives on a new report on high volume fly ash (HVFA) concrete. There will be another short ballot in April following which the document can go to TAC. The committee is involved in responding to the TAC suggestions on ACI 232.2R, Use of Fly Ash in Concrete. A substantially revised ACI 232.1R, Use of Natural Pozzolans in Concrete, has been completed. Karthik Obla is the chair of ACI 232.

301 – Specifications for Structural Concrete - ACI Committee 301 is working on several revisions to the specification in this cycle. Resolutions of ballots have resulted in revisions to the sections on lightweight concrete, mass concrete, shrinkage compensating concrete, architectural concrete, reinforcement and tilt up concrete. In the sections on concrete materials, Section 4, committee revisions were approved to change requirements for slump to allow selection by the contractor among other aspects, to change the age of test records and other smaller but significant revisions that typically cause problems on projects.

The committee is also working on including requirements for alkali silica reactions. The committee will review developments in ACI 318 as the reorganized code is published, especially the new chapter on Construction Documents to ensure it properly covers requirements in the code. Committee-approved revisions do not assure they will appear in the final document because of the intervening review process. ACI 301 is working toward completing its revised specification by 2014 and will follow a tough schedule of bi-weekly conference calls to address ballots. Colin Lobo maintains representation on ACI 301 

318 – Building Code for Structural Concrete - The committee continues its frantic pace of achieving consensus on a reorganized member-based code. The committee plans to complete this reorganized fode by Fall 2013, following which an ACI review process and public comments have to be addressed. The chapters on materials and associated commentary have been completed. Some code revisions that impact concrete materials include revisions to some of the defined durability exposure classifications and requirements to concrete, and to include reference to ASTM C595 on blended cement that permits up to 15% limestone.

Other minor changes are being proposed if the time and opportunity exists. The committee reiterated a decision that the 318 Code is written to the Licensed Design Professional and contractors have no responsibility for code requirements or to review requirements in the code. This is necessary as a new chapter on Construction Documents is being finalized with significant comments in previous balloting. Colin Lobo maintains representation on ACI 318.

325 – Concrete Pavements - The committee currently has five documents under development or revision. The report ACI 325.9R Guide for Construction of Concrete Pavements has been completely revised and the committee is currently responding to TAC comments. The committee has received tentative re-approval of ACI 325.12R-02: Guide for Design of Jointed Concrete Pavements for Streets and Local Roads which was revised by NRMCA's Brian Killingsworth, making U.S. Customary units as primary and corrected the design thickness tables, while also addressing a few editorial issues. A complete revision with updated thickness tables and other technical revisions will begin immediately and will be lead by Killingsworth.

The committee is developing ACI 325.XR Report on Precast Concrete Pavements - State of the Practice which is based upon work completed by Tayabji for SHRP2. The SHRP2 document has become the basis for an ACI design and construction report for precast and prestressed pavements which will be reviewed by the committee over the next few months. The committee is also developing ACI 325.YR Proportioning, Quality Control and Evaluation of Concrete Pavement Strength Relationships. The document is complete and is being prepared for balloting by the Fall 2013 Convention. A revision is underway of 325.11R Accelerated Techniques for Concrete Paving. Work is nearly complete and will be balloted in the next few months. The effort will harmonize with the proportioning document. Killingsworth will ensure that considerations for streets and local roads will be included in all documents. Brian Killingsworth maintains representation on ACI 325 on concrete pavements.

327 - Roller-Compacted Concrete Pavements - Brian Killingsworth will maintain representation on this committee. Current activities include resolving negative votes on the report ACI 327.XR Report on Roller-Compacted Concrete Pavements. The committee has also initiated development of an RCC specification for materials and construction to supplement report 327.XR.

329 – Performance Criteria for Materials for Ready Mixed Concrete - The committee reviewed the process for a new guide document on performance requirements for ready mixed concrete. It should be available as a Committee 329 report by Fall 2013. The committee will make a request TAC to develop a guide specification on performance requirements for concrete and with this development will suggest revisions to ACI 301 and 318 for future consideration. Some of NRMCA-developed recommendations to specifications will be used for this purpose. The committee is also developing a standard presentation discussing the benefits of evolving to performance-based specifications for improved quality and to support sustainable construction. Colin Lobo and Karthik Obla maintain representation on Committee 329.

330 – Parking Lots - In pursuit of the upcoming 330.XR Guide for the Design and Construction of Concrete Site Paving for Industrial Pavements and Trucking Facilities guide and specification, the ACI 330 Committee completed review of two more chapters, leaving just four remaining chapters to complete. These chapters will be reviewed and discussed prior to the fall ACI meeting with the goal to submit the entire document to Technical Action Committee (TAC) after that meeting. This document with be in addition to the existing ACI 330R-08 Guide to Design and Construction of Concrete Parking Lots. In addition to review and collaboration on comments, the group also heard a presentation from TC Pavements regarding its software on design of pavement sections utilizing shorter panels. Amy Miller maintains representation on Committee 522.

ACI 332 – Residential Concrete - The committee continues to work on finalizing the 2013 version of the Residential Code Requirements for Structural Concrete (ACI 332-13) and Commentary. At the urging of the ACI Technical Activities Committee (TAC), the committee has developed a section in the standard on concrete durability that follows closely the durability requirements of ACI-318, Building Code Requirements for Structural Concrete. NRMCA worked with other members of the committee to develop new definitions for durability classes specifically for residential concrete to address freezing and thawing, sulfate and chloride exposure. Despite a more complex process for identifying mixture requirements for residential concrete as a result, the requirements for concrete mixtures remain similar to past versions of the residential code. NRMCA is currently developing examples for the commentary to simplify the process of identifying concrete requirements. Public comments for the new standard will be issued in the next several months. Lionel Lemay maintains representation on this committee.

522 – Pervious Concrete - The committee discussed the upcoming ACI 522.1-12 Specification for Concrete Pervious Pavement document.  This committee reviewed public comments at the prior ACI meeting and its response submitted to TAC. The committee continues to wait for TAC approval before the document can be published. The committee also passed a ballot for acceptance of standard details for pervious concrete pavements that will be a supplement to 522R and will be posted in the ACI Concrete Knowledge Center.

Various other subjects were discussed at the committee meeting, including an update from Dr. John Kevern, University of Missouri, on cost effective solutions for density testing, hydraulic design of pervious concrete shoulders, silica fume optimization in pervious concrete, use of pervious hollow core precast sidewalk panels, and curing results of polymers and lightweight aggregates. Jereme Montgomery, Nebraska Concrete and Aggregates Association, discussed his research on comparison of fresh versus hardened density tests. Dan Biddle, FORTA corporation, gave a presentation on use of macro-synthetic fibers in pervious.

Updates from various organizations were presented, including NRMCA, ASTM, ASCE, TRB and a presentation from Scott Erickson, incoming chair for National Pervious Concrete Pavement Association. Lastly, a new subcommittee was formed to look at creating specifications for non-pavement pervious concrete applications. Amy Miller maintains representation on Committee 522.

330 – Parking Lots - In pursuit of the upcoming 330.XR Guide for the Design and Construction of Concrete Site Paving for Industrial Pavements and Trucking Facilities guide and specification, the ACI 330 Committee completed review of two more chapters, leaving just four remaining chapters to complete. These chapters will be reviewed and discussed prior to the fall ACI meeting with the goal to submit the entire document to Technical Action Committee (TAC) after that meeting. This document with be in addition to the existing ACI 330R-08 Guide to Design and Construction of Concrete Parking Lots.

In addition to review and collaboration on comments, the group also heard a presentation from TC Pavements regarding its software on design of pavement sections utilizing shorter panels. Amy Miller maintains representation on Committee 522.

555 – Recycled Materials - Karthik Obla maintains representation on ACI 555. The document Removal and Reuse of Hardened Concrete is undergoing revisions and will include discussions on crushed returned concrete aggregates based on research work conducted at the NRMCA Research Laboratory. There will be two sessions on recycled materials in concrete and is likely to feature presentations by NRMCA engineers on wash water and crushed concrete aggregate.

Sessions - There were a number of sessions on green cements and fly ash in honor of Dick Stehly. ACI provides access to presentations made during the convention.

The U.S. Bureau of Reclamation presented some one-of-a-kind tests; the Bureau broke a 3 x 6 feet concrete cylinder in a 5 million lb. machine. It has a 1.25 cubic yard concrete mixer and made concrete with 3 in. aggregates; it did tension tests on 18 in. diameter cores; various concrete abrasion tests and shake table to see how dams hold up.

• ACI has developed a new disaster reconnaissance committee that will quickly survey disaster areas.

• An innovative task group has been developed for concrete wind turbine towers.

• Anne Ellis, with AECOM was elected as the incoming ACI president. Ms. Ellis worked at NRMCA as a promotion engineer in the 1990s.

• Colin Lobo, NRMCA, was presented with the Henry C. Turner medal "for the many contributions to the concrete industry through his work in ACI committees that have resulted in better concrete for pavement and structures".

The industry’s premier driver training program is online and totally self-directed so a supervisor or company trainer is not needed. Instead, NRMCA's Concrete Delivery Professional Certification (CDP) Program is lead by a voice-over instructor whose words are seen in subtitles that support drivers with reading or hearing difficulties. Its design allows mixer drivers access through NRMCA’s Web site at any time, using any internet connection.

Each lesson is just 20 minutes long so a learning module can fit between loads or can be spontaneously accessed on slow or bad weather days at the plant. Lessons also have a stop/start feature, making CDP participation adaptable to a driver’s ever-changing work schedule. For more support, CDP-Online directly coordinates with an optional textbook.

 

Exams are online as well, so the requirement for a third-party proctor has been eliminated, saving your company time and money. Finally, the price has not increased since its initial launch yet the material and delivery system are state-of-the-art. With producers’ need to have cost-effective skill reinforcement for their remaining driving pool, CDP Online gives your frontline representatives the advantage of being the most efficient, skilled and productive driving force representing your business.

Whether the senior person who has human capital, strategic and financial responsibilities, or an HR professional new to the ready mixed concrete industry, the Operations Safety Environment Committee’s HR Task Group invites you to participate with a group of your peers. The HR Task Group meets face-to-face every spring and fall. Plan ahead: the next meeting is Saturday, September 21, in Las Vegas. 

The HR Task Group’s goal is to serve as an important ready mixed concrete, industry-specific, resource that provides insight and stimulates new ideas. Challenges abound with upcoming changes in drivers’ hours of service, labor and employment laws and regulations, health care reform and hiring challenges, to just scratch the surface. Meet with others who walk in your shoes: share your knowledge while enhancing your career.

There have been significant issues raised in the last year about the Toxic Release Inventory (TRI) Reporting Program under the responsibility of the U.S. EPA:

 

• Do you know what your responsibilities are?

• Do you know what the thresholds are for reporting?

• Do you know what the liabilities are for not reporting? 

• Do you know what heavy metals may be in your concrete making materials that would trigger reporting? 

• Do you know where to look for information?

NRMCA has certified the first Environmental Product Declaration (EPD) for concrete in North America. The EPD covers 1,479 concrete mixes produced at eight concrete plants owned and operated by Central Concrete, Inc., a U.S. Concrete company. Located in the San Francisco Bay Area, Central Concrete is the first concrete company in North America to receive a verified EPD. The EPD was independently verified and certified under the NRMCA EPD Program which was established in 2012 to enable its members to meet new requirements in LEED v4 and the Architecture 2030 Challenge for Products.

Central Concrete engaged LCA consultant Climate Earth to conduct a comprehensive LCA on over 1,400 mixes produced at eight different plants. It followed the North American Product Category Rule for Concrete developed by the Carbon Leadership Forum, relevant international standards and the NRMCA EPD Program Instructions to complete the EPD. The LCA and EPD were independently verified by Athena Sustainable Materials Institute. As required by the international standards, NRMCA published the EPD on its Web site.

NRMCA’s 8th Annual International Concrete Sustainability Conference, May 6-8, at the Hotel Sofitel San Francisco Bay will explore the latest concepts in green building. Over 60 world renowned speakers will present on topics ranging from green concrete and low-impact development to life cycle assessment and functional resilience along with the latest trends in green building, including Environmental Product Declarations (EPDs), Corporate Social Responsibility (CSR) Reporting and Health Product Declarations (HPDs).

Organizations represented during the technical sessions include Stanford University, Massachusetts Institute of Technology (MIT), University of Cambridge, University of California at Berkeley, Lawrence Berkeley National Laboratory, FHWA, PE International, Climate Earth, Skidmore Owings and Merrill, Arup, AECOM and Wildlife Habitat Council just to name a few. The Closing General Session on Wednesday, May 8, from 3:30 - 5 p.m. will feature a panel discussion titled Transparency and Material Ingredient Disclosure: What Google is Doing to Keep its Buildings Healthy. The panel will include representatives from Google, DPR Construction, KPFF Consulting Engineers, Central Concrete, MIT, and BASF.

Media articles on Congress, transportation infrastructure, regulation, taxes and other subjects, each of which relate to the ready mixed concrete industry, are updated each week by NRMCA's Government Affairs staff. To access the most recent compilation of articles - for the Week of April 15 - 19, please click here.

NRMCA's Technology in Practice series cover brief technical topics in the popular "What?, Why? And How?" format and are developed as educational topics for ready mixed concrete industry technical personnel. The topics are selected and developed by the NRMCA Research, Engineering and Standards (RES) Committee. NRMCA releases two more topics in the series:

TIP 9 – Density of Structural Lightweight Concrete – discusses the relationship between oven-dry density, equilibrium density and fresh bulk density of lightweight concrete. The density of lightweight concrete is critical when used for design load on structural members, fire rating of building assemblies and overall mass of a structure in seismic conditions. The TIP discusses procedures used in ASTM C567 to calculate or measure the density of lightweight concrete in different moisture conditions and to develop information required in project submittals.

TIP 10 – Mixing Water Quality for Concrete – addresses the process of qualifying non-potable sources of water, such as well water or mixer wash water, for use as mixing water in concrete. It discusses the details of ASTM C1602, Specification for Mixing Water and the testing requirements to qualify non-potable sources of water for use in concrete.
