Hydration Kinetics of High-Volume Fly Ash Mixtures for Concrete Paving Applications

Project Information

Project ID: 
FHWA-PROJ-14-0005
Project Abstract: 

Develop an understanding of the chemistry and phases that occur in fly ashes derived from different sources of coal and produced by different power plants. We will track the chemical and phase changes that occur during the hydration of cement pastes containing fly ashes and use this information to investigate ways of speeding up the reaction.  When this information has been developed we will investigate the chemistry of the scaling resistance of these concretes to deicing chemicals.

Goals:

Accelerate the setting time of very high-volume fly ash mixtures so they can be used in conventional concrete paving applications.
