ABSTRACT

Sulfate attacks that occur naturally in soil and groundwater where structures are located, to minimize damage to concrete structures due to external influences. Immersion carried out based on ASTM 1012 Concrete soaked for 28 days with 2 types of sulfate solution is aluminum sulfate Al2(SO4)3 and sodium sulfate (Na2SO4) with a concentration of 10%. The test results show that compared to polymer light-weight concrete under normal conditions and polymer light-weight concrete under sulfate immersed conditions, the compressive strength of concrete with epoxy resin substitution is higher than the compressive strength of concrete that has been immersed in sulfate solution. The test results show that the compressive strength of 28 days of age under normal conditions produces maximum compressive strength compared to concrete in conditions that have been immersed for 28 days experiencing a decrease in compressive strength due to sulfate attack.
