摘要：

Changes in physical and chemical properties in the mortars with different replacements by fly ash and silica fume when immersed in 2% H2SO4, 10% Na2SO4 and 10% MgSO4 solutions for 3 years were investigated. The long-term exposure test data showed that the replacement of portland cement by fly ash and silica fume effectively improved the resistance of the mortar to the sulfuric acid and sulfate solution attack. However, the replacement percentage by fly ash and silica fume necessary to prevent the sulfuric acid and sulfate solution attack varied significantly depending on the type of sulfuric acid and sulfate solutions.
