Evaluation of Compressive Strength of Mortar Replaced to High Volume Blast Furnace Slag

고로슬래그 미분말을 다량 치환한 모르타르의 압축강도 평가

With blast-furnace slag is a by-product generated when pig iron is produced. It has been used as the concrete admixture due to high reactivity. However, It causes low strength development during early age. In order to make up for this drawback, in this study, we evaluated compressive strength of mortar replaced with high volume blast-furnace slag. Experimental results, Compressive strength of mortar based on blast-furnace slag is affected by cement type, substitution rate of blast-furnace slag and pH after mixing.
