SLAG CEMENT REINFORCED BY THE COMBINATION DOPING OF LIMESTONE AND ANHYDRITE

摘要

The hydration performances of slag cement mixed by limestone and anhydritehave been studied. The phase compositions andmicrostructures of the hydrates were determinedand analysed by XRD and SEM. It is discoveredthat when slag cement is mixed with limestoneand anhydrite. the hydrations of the clinker andslag are speeded. The amount of ettringite andhydrate calcium silicate are increased and the me-chanical strength of slag cement are enchanced.
