Effect of Sodium Sulfate Solution Coupled with Wetting-Drying Cycles on the Properties of Nano-Alumina-Modified Concrete.

The degradation of concrete caused by sulfate attack poses a significant challenge to its durability. Using nanomaterials to enhance the mechanical and durability properties of concrete is a promising solution. A study of the durability of nano-alumina (NA)-modified concrete by sulfate erosion was carried out.
