Abstract

The invention discloses a resin concrete, which is characterized in that the concrete is made of the following materials by weight proportion: 1 to 20 weight proportions of unsaturated polyester resin, 50 to 80 weight proportions of aggregate, 3 to 15 weight proportions of powder and 0.5 to 5 weight proportions of admixture. The admixture consists of low shrinkage agent and hardener. By reducing content of the resin of the resin concrete and adding appropriate admixture, novel high-efficiency concrete with high strength and formed product thereof are obtained. The formed product is characterized by low cost, high strength, non-crack and good physical property. More particularly, the invention adopts MC-869 polyester resin as raw material, which reduces consumption and dramatically improves performance index compared with similar product.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to resin concrete and its formed products. Background technique [0002] Resin concrete is a composite material made of synthetic resin (Polymer Resin) plus appropriate amount of curing agent, toughening agent, diluent and filler as adhesive, sand and stone as aggregate, after mixing, molding and curing. Because of its good corrosion resistance, wear resistance, water resistance and frost resistance and mechanical properties, it makes up for the shortcomings of cement concrete such as low tensile strength, small tensile strain, poor crack resistance, and brittle failure. The cured resin concrete has strong resistance to atmospheric moisture, chemical media, bacteria, etc. Therefore, it is mostly used in relatively harsh environments. In recent years, with the rapid development of China's economy and the continuous advancement of science and technology, various new building materia...
