EFFECT OF STONE POWDER ON STONE CHIPPINGS CONCRETE
摘要
In this paper,the effect and mechanism of calcareous stone powder with size less than 0. 074mm are investigated in stone chippings concrete. The results show that the stone powder can participate in hydration reaction and acts as crystal nucleus in hydration process, namely. it has hydration activity to an extent. The strength of stone chippings concrete is enhanced and the easy-mixing capacity of the concrete mortar is modified when stone chippings contain a proper amount of stone powder. The stone powder has little effect on the wearability of the concrete.
