METHOD FOR PREPARING CEMENT POLYMER COMPOSITES MATERIALS HAVING SUPER STRENGTH PROPERTIES

摘要

The present invention relates to a method for producing an ultra high strength cement polymer composite material, comprising a composition of an ultra high strength cement composite material composed of portland cement, pulverized slag, silica fume, anhydrous gypsum, thermoplastic resin, aggregate, and steel fiber. The cement mixture is cured in hot water in water at a temperature of 60 to 90 ° C. and heat cured at a temperature of 150 to 200 ° C. to produce an ultrahigh strength cement polymer composite material.;In the method of the present invention, by adding a thermosetting resin and heat treatment at a temperature above the softening point, the resin softens and penetrates into the internal pores to reduce the pores, and penetrates into the internal microcracks generated by heating curing to form a film to enhance toughness. It can be seen that it is possible to produce polymer composite ultra high strength cement composite materials without complicated manufacturing processes such as polymer impregnation operation.
