Evaluation of ASTM C 494 Procedures for Polycarboxylate Admixtures Used in Precast Concrete Elements

This project will provide the Texas Department of Transportation (TxDOT) with revised tests, specifications, and recommended practices to use and inspect precast concrete (conventional and self consolidating concrete [SCC]) containing polycarboxylate admixtures (PC). An overarching objective of this project is to increase the understanding of the effect of polycarboxylate (PC) High-Range Water-Reducers (HRWR) on the performance of concrete mixtures, with a special focus on concrete mixtures that will be used in precast concrete beam applications. The project will leverage the results of Inter-agency Contract (IAC) No. 46-3MTIA034: Evaluation of Long-Term Durability of Concrete, which addresses potential mechanisms for cracking in girders cast at Texas precast plants, typically appearing 18-24 months after casting.
