Abstract
In the present paper, cement paste and cement and fly ash paste specimens with and without epoxy coating are partially immersed in saturated sodium sulfate solution at 20°C for 6 months. The evaporation speed of solution and development of compressive strength of specimens are measured. The results show that epoxy coating cannot only improve the sulfate resistance of upper part of paste above solution but alos of lower part under solution. According to XRD analysis, chemical sulfate attack is more likely to be the mechanism resulting in the failure of concrete elements partially immersed in sulfate environment. The epoxy coating can alleviate the chemical sulfate attack and improve the sulfate resisting performance of concrete.
