Abstract

This research aims to study the acid-resistant property of geopolymer mortars containing glass waste. The river sand was replaced with glass waste at 0, 10, 20, 30, 40, 50, 60, 80 and 100% by volume. The test result was also compared with cement mortars containing glass waste. The sulfuric acid resistances were collected at 7, 14, 28, 56, 84, and 120 days. The test results showed that the sulfuric acid resistance slightly decreased with the increase in glass waste contents. However, the geopolymer mortar with 100% glass waste still exhibited better sulfuric acid resistance than that of Portland cement mortar as per ASTM C109/C109M. The glass waste could be applied in geopolymer mortar and concrete for the construction industry. The use of glass waste to produce geopolymer composite not only reduces Portland cement consumption but also reduces the environmental problems from waste glass.
