Quartz powder with different fineness were added into alkali activated slag cement to reduce the drying shringkage of the hardened cement paste. Experimental results showed that partially replacing the slag powder with quartz powder will reduce the water requirement of normal consistency, dry shrinkage and early age compressive and flexural strength of alkali-activated slag cement (AASC), however, the flexural/compressive strength ratio and the fracture toughness will be increased and so does the later strength. The fracture section of specimen of quartz powder modified alkali-activates slag cement paste has a rougher texture than that of pure alkali-activates slag cement paste.
