| Abstract: | Cracks may appear in the period of operation as well as in the period of construction of concrete dams. Permanent thermal insulation is necessary for concrete dam to prevent cracking in the period of operation. A permanent compound plate of thermal insulation is suggested:it consists of a foamed polystyrene plate and a reinforced concrete plate. A permanent compound plate of thermal and water insulation is suggested for the upstream face of RCC dam: it consits of a waterproof membrane, a foamed polystyrene plate and a reinforced concrete plate . |
