Engineering Properties of Zero-Cement Mortar with Variation Replacement Ratio of Incineration Waste Ash and Gypsum

석고종류 및 소각장애시 치환율 변화에 따른 고로슬래그 미분말 활용 무시멘트 모르타르의 공학적 특성

In this study, industrial by-products including blast furnace slag, incineration ash and waste gypsum were used with recycled fine aggregates to manufacture the zero-cement mortar.The replacement ratio of dihydrate gypsum and anhydrite gypsum was fixed as 0 and 10%, the replacement ratio fo WA1 was fixed as 0.5% and 1.0%, respectively. It could be identified that when the replacement of gypsum was 10% and WA1 of 1.0%, the strength could be in the range of normal strength.
