Activation of theslag cement was performed using a composite activator. Experimental resultsshow that the performance of the cement is remarkably improved. The fineness and specific surface area of the ce-ment are increased by 23.7% and 1.4% , and 3d flexural strength and compressive strength are enhanced by20.9% and 22.9% , respectively. Microstructure and phase composition of the hydrates were analysed by X- raydiffraction(XRD) and scanning electron microscopy(SEM). The results indicate that Ca( OH)2 in the hydratesdecrease obviously. The morphology of the other hydrates appears to be flocculent, with a dense structure. The im-provements of the properties is related to the microstructural changes.
