Abstract

This paper describes the results of experimental study on thermal properties and strength developments of mass concrete substituting fly-ash for cement less than 45%. We obtained the following results. 1. By using fly-ash to mass concrete, the temperature of concrete could be lower than that of non fly-ash concrete. 2. Using fly-ash to mass concrete could be more workability of concrete. 3. The compressive strength of core test piece of mass concrete substituting fly-ash for 45% cement could be not lower than that of the test piece by standard cure.
