Abstract: This paper presents the effect of fine aggregate on the resistance of mortar to sulphuric acid attack. We used acid-resistant cement, which constrains the amount of calcium hydroxide formed by the hydration of ordinary portland cement. When river sand is used as fine aggregate, resistance of mortar to sulphuric acid improves remarkably using acid resistant cement. We found that the resistance to sulphuric acid is high when blast-furnace slag sand is used; on the other hand, the type of cement has very little effect on the resistance.
