Using the large heat capacity materials ( basalt and smelting slag ) as aggregate and Portland cement as the gelatinizer, the heat storage concrete with ground slag and silica power for increasing the mechanical properties of concrete and a certain proportion of graphite powder for improving the thermal performance of the heat storage material is prepared. The study results show that the compressive strength and flexural strength of the heat storage concrete are great in 200~500℃, the average specific heat of the concrete is 2272J/(kg?K) in 300~500℃, and the theoretical heat storage value of the concrete is 335.75kWh/m3.
