Performance Criteria for Ready Mixed Concrete: Where Are We Today? (Part 2)-Concrete Slabs-on-Ground and the Practicality of Performance-Based Specifications (Recorded Presentation)

Concrete Slabs-on-Ground and the Practicality of Performance-Based Specifications (Recorded Presentation)

Video Transcription

Video Summary

The speaker discusses the P2P initiative, addressing challenges in the concrete industry, particularly for slabs on the ground. The focus is on performance-based approaches, emphasizing liability, responsibility, and achieving consistent results in a competitive bidding environment. Prescriptive specifications are currently more reliable for ensuring quality, focusing on factors like compressive and flexural strength, shrinkage, and finishability. The talk highlights issues such as the impact of admixtures on concrete set times, the application of calcium chloride, and difficulties with fly ash. The speaker also underscores the importance of measurable, accountable, and timely performance criteria for ready-mix producers, stressing the need for improved industry dialogue and understanding of mix components. Despite advancements, the speaker believes the industry isn't fully ready for performance-based specifications without further development and validation.
