The Experimental Study on Performance of the High-Content Slag Cementitious Materials

The research adopts the raw material of 89% slag with the composite activators and the compressive strength, hydration heat, temperature and expansion property of the material are studied. And the new cementitious material is obtained with the properties of low-heat and small expansion, convenience-confect, easy-operation and need no mass production. This material has the remarkable economic profit and good application foreground especially in the mass grouting engineering.
