HYDROPHOBIC EMULSION MODIFIED RAPID-CURING CONCRETE COMPOSITION CAPABLE OF IMPROVING THE TENSILE STRENGTH OF CONCRETE AND A REPAIRING METHOD OF A CONCRETE STRUCTURE USING THEREOF

摘要

PURPOSE: A hydrophobic emulsion modified rapid-curing concrete composition and a repairing method of a concrete structure using thereof are provided to improve the durability of concrete by mixing a hydrophobic emulsion copolymerized with butyl acrylate resin.;CONSTITUTION: A hydrophobic emulsion modified rapid-curing concrete composition contains 5~25wt% of cement group binding material, 30~60wt% of fine aggregate, 20~50wt% of coarse aggregate, 0.5~5wt% of water, and 0.1~6wt% of hydrophobic emulsion. The hydrophobic emulsion includes hydrophobic acryl and a butyl acrylate resin. 80~99wt% of hydrophobic acryl and 1~20wt% of butyl acrylate resin forms 100wt% of hydrophobic emulsion.;COPYRIGHT KIPO 2010
