METHOD OF WATERPROOFING CONCRETE BRIDGE USING WATERPROOF COMPOSITION OR WATERPROOF SHEET OF BRIDGE OR CONCRETE STRUCTURE

摘要

The present invention relates to a method of waterproofing a concrete bridge using a waterproof composition or a waterproof sheet of a bridge or a concrete structure. The waterproof composition includes at least one ultrafine filler selected from the group consisting of acrylic polymer, fine clay mineral, wood pellet, calcium carbonate (CaCO_3), and titanium dioxide (TiO_2), and at least one property improver selected from the group consisting of nano carbon material, anionic or non-anionic dispersant, ethyl cellulose, polyacrylate, silicone antifoam, isothiazoline, and derivative. The waterproof sheet includes a first layer including silicone, acrylic, rubber or hot melt adhesive; a second layer configured by non-woven including fine bark, rice straw, or wood pellet; a third layer obtained by agitating and heating the waterproof composition to be hardened; and a fourth layer including silicone, acrylic, rubber or hot melt adhesive, polymer film, and meta kaolin.;COPYRIGHT KIPO 2020
