An inorganic concrete repair material of high resistance to erosion and abrasion is mainly prepared by mixing the raw materials of silicate minerals, a volcano dust mixture, silicon oxide particles, sulphoaluminate minerals, high molecular weight polymers of fatty alcohol polyoxyethylene ether, cellulose ether, polypropylene fibers, silicon oxide solid particles, etc. As the material contains ingredients for reducing moisture losses and evaporation, ingredients for preventing and reducing shrinkage, ingredients for resisting cracks and ingredients for improving bonding strength and erosion and abrasion resistance strength, the use of the material has the advantages of adjustable operation time, good bonding properties, low shrinkage, high crack resistance, approximate elastic modulus and coefficient of linear expansion with concrete, little possibility of falling off a base material, high bonding strength and high erosion and abrasion resistance strength. Epoxy repair materials can be replaced by the material in the concrete flaw repair, particularly in the repair of concrete parts destroyed by water for the purpose of resisting current erosion. The material is nontoxic, tasteless, and convenient for construction in practical application.
