- Abstract
- This study focuses on high durability mortar against sulfuric acid attack by replacing binary and ternary blend of binder with fully substituted Air-Cooled Blast Furnace Slag (ACBFS) fine aggregate. Two replacement ratio of binder were considered in this study and ten types of binder mix were designed to conduct experiment. And cementitious materials with self-healing capability were prepared in order to apply for theses mortars. Each specimen was manufactured into 3 cm diameter with 5cm height in cylindrical mould. After demolding, specimens were water cured for 28 days. All specimens were immersed into 3% concentrated solution for 60 days and solutions were replaced regularly in consider with loss of sulfuric acid concentration. Mass change of all specimens was measured after removing detached particles gently. From 60days observation, it was shown that specimens with ACBFS performed high resistance to sulfuric acid attack compared to normal fine aggregates in same binder mix. Also, ternary blend mix showed higher resistance than binary blend specimens.
