The concrete Krasnoyarsk hydroelectric station dam, at its highest point 124 meters high, is approximately 1100 meters long and is located in a relatively narrow rocky canyon of the Yenesey River. The amount of concrete in the dam and hydroelectric station building is 5.5 million cubic meters. The concrete operations were accomplished under severe climatic conditions - the frost-free period was 102 days long and temperature ranged from -54 to 37C. Great requirements were levied on the concrete with regard to strength, imperviousness to water, cavitation resistance, cold resistance and fracturing resistance. This report discusses the construction problems and considerations.
