Spaces Available for December Concrete Specification Class on West Coast

NRMCA is offering its information-packed one-day course, Handling Concrete Specifications, Low Strength Problems and Mixture Submittals, intended for concrete producers, contractors, engineers and testing labs on Tuesday, December 3, in Sacramento, CA and Wednesday, December 4, in Glendora, CA. Dealing with concrete specifications, troubleshooting low strength problems and ensuring proper mixture submittals can be expensive and time consuming. This one-day course will get into code and specification requirements (ACI 318, 301, ASTM C94) governing ready mixed concrete, including exposure categories in the ACI Building Code 318-11. It will suggest specification revisions for all around benefits in performance and cost which is based on a specification guideline document. The guideline document is the result of review of numerous concrete specifications (Section 03300) belonging to large owners and has been reviewed and supported by NRMCA's Research Engineering and Standards Committee.  

The course will cover the analysis of strength test results to identify causes for low strength problems and provide guidance to track compliance with specification requirements. Non-destructive testing techniques such as the Rebound Hammer, core testing, evaluating core test results for acceptance and assignment of responsibility will be discussed. The course also provides necessary details required for an efficient concrete mixture submittal following the ACI 318 Flowchart for Selection of Concrete Mixtures.

Course instructors are Luke Snell, P.E., FACI, FASCE, Western Technologies and Karthik Obla, Ph.D., P.E., vice president technical services at NRMCA. Producers, contractors, engineers and testing labs will find the discussions on investigating low strength problems and specifications very helpful to address issues that impact partnering, project cost and schedule. Upon successful completion of the course, attendees will earn 8 professional development hours, a certificate of completion and credits toward NRMCA’s STEPS program.
