A COMPOSITION OF POLYMER CEMENT MORTAR FOR REPAIR OF DETERIORATED CONCRETE STRUCTURES AND PREPARATION METHOD THEREOF

摘要

A composition of polymer cement mortar is provided to repair deteriorated concrete structures and give adiabatic and waterproof properties to the polymer cement mortar, thereby minimizing thermal expansion/contraction with a base layer concrete structure. A composition of polymer cement mortar for repair of deteriorated concrete structures includes 30-50wt% of a resin emulsion composition with respect to 100wt% of powder that consists of 30-50wt% of cement, 15-25wt% of silica (60-100mesh), 15-25wt% (100-200mesh) of the silica, 3-5wt% of pearlite, 15-25wt% of glass bead (less than 100mesh), 1-3wt% of sodium compound, 2.5-5wt% of fluosilicate salt compound, and less than 1wt% of a foaming agent, thickner, and dispersant. The resin emulsion composition consists of ethylene vinyl acetate emulsion and butyl acrylate styrene copolymer emulsion mixed at ratio of 2-5:1-3 by weight.
