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 in which the High Volume Fly Ash concrete is placed while monitoring and testing these structures. The proposal also suggests the use of a short course that will be made available by means of streaming video or DVD for use in classrooms and continuing education courses.
The key project objective is to improve understanding of infrastructure materials, specifically how to use higher fly ash amounts in concrete and obtain the performance needed for long-lasting concrete highway pavements and structures.
