Project description

The objective of this project is to evaluate properties of fresh and hardened concrete comprising portland-pozzolan cement with respect to current Utah Department of Transportation (UDOT) specifications for cast-in-place concrete barriers. Specifically, the effects of a potentially higher water-cementitious materials ratio on the performance of the concrete in fresh and hardened states will be investigated, as well as methods of lowering the water-cementitious materials ratio to increase compliance with specifications.
