QUICK HARDENING REPAIRING MORTAR COMPOSITION AND CONSTRUCTING METHODS USING THEREOF

摘要

The present invention relates to a quick hardening repairing mortar composition comprising 20-80 parts by weight of methyl methacrylate, 10-60 parts by weight of prepolymer, 5-30 parts by weight of curing agent, 10-20 parts by weight of calcium sulfoaluminate, 5-1,000 parts by weight of filler, and 1-5 parts by weight of water reducing agent based on parts by weight of cement; and a construction method using the same. The present invention provides the quick hardening repairing mortar composition which is capable of reducing construction time by quickly hardening in construction, and providing enough compressive strength, flexural strength, bond strength, and durability required for a mortar composition. Moreover, the present invention has an effect for maintaining stable reinforcement by preventing separation from an old and new bonding layer by flowing and integrating the quick hardening repairing mortar composition through a hole in a reinforcement structure installed in a damaged part.
