Abstract

The invention relates to environment-friendly foamed high-performance concrete and a preparation method thereof. The environment-friendly foamed high-performance concrete consists of cement, coal ash,sand, modified rubber, silicon ash, waterproof emulsion and a foamed material, the modified rubber is prepared by virtue of the reaction of terminated-hydroxyl liquid nitrile rubber, tetrabutyl titanate, water, ethanol, silicasol, sodium silicate and oxalic acid, the waterproof emulsion is prepared by virtue of the reaction of 2-acrylamide-2-methallyl sulfonate, 2-ethylhexyl acrylate, water, SE-10 emulsifier, tetraethyl orthosilicate, silicasol, ammonium persulfate and acrylic acid, the foamed material is prepared by virtue of the reaction of hydroxyl-terminated silicone rubber, ammonium oxalate, ethanol, nano titanium dioxide, urea, KH-550 coupling agent and poly N-isopropylacrylamide, and the nano titanium dioxide is prepared by virtue of the reaction of tetrabutyl titanate, stearic acid, oleic acid, ethanol, polyoxyethylene stearates SG-12, water and glycerinum. The environment-friendly foamed high-performance concrete provided by the invention is excellent in heat preservation performance and waterproof performance.

Description

technical field [0001] The invention relates to the field of concrete, in particular to an environment-friendly foamed high-performance concrete and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living materials and economic level, people have higher and higher requirements for the environmental protection, safety and performance parameters of building materials. Although concrete materials have excellent mechanical properties, concrete has partial thermal insulation and waterproof performance. Low defects make it difficult to expand the application of ordinary concrete in the medium and high-grade fields. Therefore, researchers in the field of concrete encourage researchers in different fields to conduct research on high-performance concrete materials. Because ordinary concrete has lower requirements on thermal insulation and waterproof performance. Therefore, concrete needs to be improved in terms of high thermal ...
