COMPOSITION FOR MAINTENANCE AND REINFORCEMENT OF CRACKS USING EPOXY RESIN AND CONSTRUCTION METHOD USING SAME

摘要

The present invention relates to a composition for maintenance and reinforcement comprising, based on 100 wt% of an epoxy resin, 5 to 30 wt% of calcium sulfoaluminate, 5 to 50 wt% of a filler consisting of aluminum hydroxide, calcium carbonate or a mixture thereof, 10 to 40 wt% of fibers, 5 to 20 wt% of a curing agent, 30 to 50 wt% of latex, 0.01 to 4 wt% of a re-emulsified polymer powder, 1 to 10 wt% of an adhesion promoter, and 3 to 15 wt% of a low shrinking agent. The composition for repairing and reinforcing cracks according to the present invention comprises an epoxy resin, a filler, a hardener, a fiber, and the like to the composition for maintenance and reinforcement, and thus provides the composition for repairing and reinforcing cracks which improves adhesion to the periphery of the cracks and increases water resistance and long-time durability at the same time.;COPYRIGHT KIPO 2017
