DURABILITY INCREASING METHOD FOR REPAIRING AND REINFORCING WATER TREATMENT STRUCTURE AND INCREASING WATERPROOF AND ANTICORROSIVE PERFORMANCE USING ENVIRONMENTALLY-FRIENDLY COMPOSITION
DURABILITY INCREASING METHOD FOR REPAIRING AND REINFORCING WATER TREATMENT STRUCTURE AND INCREASING WATERPROOF AND ANTICORROSIVE PERFORMANCE USING ENVIRONMENTALLY-FRIENDLY COMPOSITION
The present invention relates to a durability increasing method for repairing and reinforcing a water treatment structure and increasing waterproof and anticorrosive performance by using an environmentally-friendly composition. According to the present invention, the durability increasing method comprises: a step (S10) of treating a surface of an object to be repaired and reinforced of a structure; a step (S20) of restoring the cross section of the object to be repaired and reinforced of a structure by a polymer mortar composition including cement, ethylene vinyl acetate (EVA)-based polymer, phenoxy resin, calcium sulfonate aluminate, a shrinkage prevention agent, a defoaming agent, a silicone water repellent, and an antirust agent; and a step (S30) of finishing the cross section of the object to be repaired and reinforced of a structure by using a finishing composition including resin, a curing agent, pigment with an average particle size of 1 to 40 m, metal oxide nanoparticles with an average particle size of 40 to 250 m, a dispersing agent, a thickener, non-silicone hybrid copolymer, a filler, and an anti-sagging agent.;COPYRIGHT KIPO 2019
