Roller-Compacted Concrete

The development of Roller Compacted Concrete (RCC) caused a major shift in the construction practice of mass concrete dams and locks. The traditional method of placing, compacting, and consolidating mass concrete is at best a slow process. Improvements in earth-moving equipment made the construction of earth and rock-filled dams speedier and, therefore, more cost-effective.

Our research has been to develop appropriate laboratory testing that represents the field conditions and to optimize the construction sequence.
