Document Type: Proceeding Paper

Part of: Roller Compacted Concrete II

Abstract:

The design, construction and performance of the first three dams constructed in Australia, using RCC are described. Aspects covered in the paper include designing for zero cohesion between RCC lifts, facing RCC spillways with conventional concrete, combining the placement of RCC and earthfill, construction of galleries, stability of unformed slopes, construction of transverse contraction control joints, testing and controlling RCC quality, the prediction of 90-day strengths by rapid curing and the performance of the dams to date including cracking and seepage.
