Performance Criteria for Ready Mixed Concrete: Where Are We Today? (Part 1)-Performance Requirements for Ready Mixed Concrete in North America

Performance Requirements for Ready Mixed Concrete in North America—Are We There Yet (Recorded Presentation)

Video Transcription

Video Summary

The presentation discusses the importance of performance requirements in concrete construction from a contractor's perspective. Emphasizing durability, strength, workability, and economic aspects, it highlights the need for proven performance backed by testing data. Case studies illustrate innovative approaches to concrete mix design, focusing on high-early strength, tremie, and mass concrete projects. The speaker stresses the value of balancing performance with constructability, challenging prescriptive specifications, and adopting a team-oriented approach. Examples include a transition from bag grout to ready-mix solutions for Tennessee bridges, optimizing aggregate blends for tremie work, and achieving thermal control in mass foundations, such as the L.A. Rams stadium. The discussion culminates in practical insights: innovate with purpose, understand construction demands, ensure early involvement, and favor economical choices over cheap ones to exceed client expectations.
