Abstract:To maintain proper temperature in the 1,500,000 cu yd of concrete in Detroit Dam, several techniques were considered. After an investigation of the heat balance in the materials, it was decieded to construct a plant for cooling the aggregate and cement. A brief history of coolingmass concrete preceeds the description of the cooling plant for Detroit Dam. The coarse aggregate is emmersed in 35 F water until the aggregate cools to 38 F. It is then drained and screened to remove excess moisture. Sand and cement are cooled by continuous hollow-flight screw conveyors through which 35 F water is circulated. Heat transfer is through the conveyor surfaces; there is no direct conteact with the cooled water.
