Project description

The research will examine: (1) material compatibility; (2) prediction methods for property development; (3) temperature and strength development management; (4) internal and external curing; (5) reducing early age cracking; and (6) improving freezing/scaling durability. Carefully controlled large scale test sections will be prepared to evaluate the proposed solutions from each phase. This large scale testing will be unique due to the ability to carefully establish and monitor the environment that the high volume fly ash (HVFA) concrete is placed in while monitoring and testing these structures.
