CEMENT-BASED SURFACE-PREPARING MATERIAL, SURFACE-PREPARING MATERIAL, CONCRETE STRUCTURE, AND METHOD FOR PROTECTING SURFACE OF CONCRETE

摘要

To provide a cement-based surface-preparing material for a surface of a concrete after a desalting treatment, the concrete showing high water content and high alkaline properties, wherein the surface-preparing material reduces the water content in the surface thereof and improves adhesiveness to a surface-coating material.SOLUTION: This invention relates to a cement-based surface-preparing material for subjecting a concrete obtained after a desalting treatment through an electrochemical corrosion-preventing method to surface preparation before a surface-coating treatment with a surface-coating material, comprising: a cement; and an anhydrous gypsum.SELECTED DRAWING: None
