Abstract

Abstract

A series of tests， including corrosion resistance， compressive strength， and microscopic analysis， were conducted on foam concrete under the combined action of chloride-sulfate composite salt solution. The study investigated the influence of the composite salt environment on the durability of foam concrete， focusing on mass change， compressive strength， and microstructure.The results indicate that under the erosion effect of the composite salt solution， a large number of white crystals formed on the surface of the specimens in the early stages. Additionally， damage to the specimens initially appeared at the edges and corners. The higher the density of foam concrete， the smaller the surface damage would be. The mass change rate of the foam concrete specimens was closely related to their density under the corrosion of the composite salt solution， and the overall mass change trend of the specimens first increased and then decreased. The resistance of foam concrete to compound salt attack increased with the increase of density， which was mainly reflected in the apparent damage， mass change， and strength change of the specimens. There was an interaction between the two salts， and the presence of chloride ions could inhibit sulfate corrosion to some extent.
