る。加えて、相対的に高価な解決法である。Repair mortar is essentially a mixture of cement and fine aggregate (usually sand) used to repair concrete surfaces. There is a need to provide a protective coating that closes affordable holes, adheres to strength and surface tightly, and can withstand deformation without peeling or cracking. In order to have these properties to a sufficient extent, the repair mortar has a relatively low modulus or "E-module" with an acceptable degree of compressive strength.
(Preferably 25,000 MPa or less). However, a decrease in elastic modulus generally means a decrease in compressive strength. Some of these problems are solved by incorporating a polymeric material into the mortar, an aqueous polymer latex, which is usually a dispersion of film-forming polymer particles or a redispersible polymer powder. This results in a significant improvement in peel resistance and a significant decrease in elastic modulus, which is achieved at the expense of reduced compressive strength. In addition, it is a relatively expensive solution.
