COMPOSITION COMPOUND FOR REPAIRING CONCRETE STRUCTURE WITH HIGH BENDING STRENGTH AND DURABILITY AND REPAIRING METHOD OF CONCRETE STRUCTURE USING THE COMPOSITION COMPOUND

摘要

PURPOSE: A composition compound for repairing a concrete structure with high bending strength and durability and a repairing method of a concrete structure using the composition compound are provided to improve the elasticity, the tensile strength, and the adhesive of the composition compound by using a liquid resin-based binder containing the mixture of n-butyl methacrylate, methyl methacrylate, n-butyl acrylate monomer, and urethane acryl oligomer. CONSTITUTION: A composition compound for repairing a concrete structure includes 5-90 weight% of a liquid resin-based binder, 5-50 weight% of filler, and 5-60 weight% of aggregate. The liquid resin-based binder includes 40-70 weight% of a resin in an acrylic syrup state, 5-35 weight% of n-butyl acrylate monomer, and 0.5-25 weight% of urethane acryl oligomer. A method for manufacturing the resin in an acrylic syrup state includes the following: A solid resin is dissolved in methyl acrylate monomer. The solid resin includes n-butyl methacrylate and methyl methacrylate. The liquid resin-based binder further includes benzoil peroxide.
