Effects of Moisture Absorption Coefficient of Alkali-Activated Slag-Red Mud Cement on Efflorescence

알칼리활성화 슬래그-레드머드 시멘트 모르타르의 흡수계수가 백화발생에 미치는 영향

In this study, moisture absorption coefficient and efflorescence properties of Ordinary Portland cement and alkali-activated slag cement mortar were assessed according to their red mud substitution ratio. Tests were conducted to determine the cause of efflorescence, which is a significant obstacle to the recycling of red mud as a sodium activator in alkali-activated slag cement, and to find a method to control efflorescence.
