Constructing method for waterproof and improved durability of concrete structures using infiltrative liquid waterproofing agent

摘要

The present invention provides a waterproofing method for forming a waterproof layer on the surface of a concrete structure using a permeable waterproofing agent, comprising the steps of: arranging a base surface of the concrete structure; First applying a paste obtained by mixing water and an impermeable waterproofing agent on cement; Applying a waterproofing solution obtained by mixing water and a permeable waterproofing agent; Secondly applying a paste obtained by mixing water and a water permeable waterproofing agent on the cement; It is constructed through the step of applying a waterproof mortar mixed with a permeable waterproofing agent; The permeable coating waterproofing agent, based on 100 parts by weight of the epoxy resin; In a solvent mixture in which 60 to 80 parts by weight of distilled water, 20 to 40 parts by weight of dimethyl sulfoxide, 30 to 60 parts by weight of petroleum ether, and 10 to 30 parts by weight of a nonionic surfactant are mixed, 50 to 70 parts by weight of polyepoxyimide Parts, 1,3,5-triglycidyl isocyanurate 10 to 30 parts by weight, isomeric octyltriethoxysilane 10 to 30 parts by weight, butanediol diglycidyl ether 10 to 30 parts by weight, tetraethoxyor A first sol-gel resin prepared by mixing 5 to 15 parts by weight of sosilane and 5 to 15 parts by weight of aminosilazane; And in a solvent mixture in which 60 to 80 parts by weight of distilled water, 20 to 40 parts by weight of dimethyl sulfoxide, 30 to 60 parts by weight of petroleum ether, and 10 to 30 parts by weight of a fluorine-based surfactant are mixed, dicyclopentyloxyethyl methacrylate 50 to 70 parts by weight, 2-phenoxyethyl methacrylate 30 to 50 parts by weight, glycidoxypropyl trimethoxysilane 20 to 30 parts by weight, zirconium butoxide 10 to 15 parts by weight, tetrabutyl titanate 10 to 15 parts by weight And a second sol-gel resin prepared by mixing 5 to 8 parts by weight of sodium hexametaphosphate; by using a permeable coating waterproofing agent that penetrates into the micropores of the concrete structure, improving the adhesion between the waterproof layer and the concrete structure, and waterproofing The present invention relates to a waterproofing method for reinforcing durability of a concrete structure using a permeable coating waterproofing agent capable of enhancing the durability of a concrete structure by improving the watertightness, strength, and durability of the constructed waterproof layer itself.
