A process for manufacturing concrete bodies at elevated temperatures including the steps of providing pre-selected amounts of cement, aggregate and water where the temperature of at least the aggregate and more likely the cement and water are heated to a temperature between about 32° C. and 45° C. The heated amounts of cement, aggregate and water are mixed at an elevated temperature within the aforementioned range and a set retarding, water reducing admixture added. The mixing is continued and the hot mixture including the set retarding, water reducing admixture is cast at an elevated temperature within the same range to provide a concrete body form or structure with improved short and long-term compressive strengths.
