NRMCA is offering its information-packed, one-day online course, Handling Concrete Specifications, Low Strength Problems and Mixture Submittals, intended for concrete producers, contractors, engineers and testing labs from October 12 - 14 from 11 a.m. to 1:30 p.m. Eastern time each day. The course will get into code and specification requirements (ACI 318, 301, ASTM C94) governing ready mixed concrete. It will address many topics, including answering the following questions: 

• What are the durability exposure classes in ACI 318 and how should be specified?
• What are the changes in the new ACI 318-14 that are related to ready mixed concrete?
• What are some specification revisions that can provide all around benefits?
• What are the causes for low strength problems and who is responsible?
• What should be on a concrete test report?
• Non-destructive testing, Coring – when and how?
• How to do a proper mixture submittal?

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.
