A blended cement containing blast furnace slag and phosphorous slag

Abstract

Blended cement containing blast furnace slag (BFS) and phosphorous slag (PS) is a new kind of cement. The total content of blended materials could increase if two additives were used. Using the same admixtures, the properties of the blended cement with 70% additives could reach the standard of 525-grade slag cement according to GB. The strength of cement with 80% additives could reach the standard of 425-grade slag cement. The tests of strength, pore structure, hydration products, inhibiting alkali-aggregate reaction, resistance to sulfate corrosion of BFS-PSC were performed.
