An Experimental Study on the Stregth characteristics of Mortar using the Blast-Furnace Slag Sand

서냉슬래그 모르터의 강도특성에 관한 연구

This experimental Study presents the strength properties of mortar Using the Blast-furnace Slag Sand. It gives following result. The 3-days and 7-days compression strength is increase as substitution rate is higher. As W/C ratio increase, the strength is decrease. The flexural strength is increase as substitution rate is higher specially. As flexural strength ratio for compression strength is each 16.7%, 21.1%, 25.4% on 3-days, 7-days, 28-days, long age flexural strength is higher than short age.
