Preparation of Non-Sintering High Strength Aggregate using Coal ash

석탄회를 이용한 비소성 고강도 골재의 제조

For substitution for crushed sand, high strength aggregate for cement and concrete using coal ash as a main material was prepared and then compared its physical properties with those of crushed sand. Effect of mix proportion change of raw materials on the property of aggregate was checked. On the basis of these experimental results we are going to comprehend the reutilization of coal ash and utilize a basic data for judging possibility the substitution of crushed sand.
