In RCD dams, like conventional concrete dams, the concrete is classified into external concrete that is used at the surface of the dam (A1, A2, Fig. 18.30), foundation concrete (A3) that faces the bedrock, structural concrete (A4) that is used in and around structural elements, and internal RCD concrete (B1 and B2) that is used inside the dam body. Thus, RCD concrete volume is estimated excluding external, foundation and structural zones, and this volume is a key point in the adoption of RCD construction method. For the zones A1 to A4 high quality conventional concrete is applied to maintain watertightness, durability, structural stability etc.
