High performance building cast-in-place concrete and preparing method thereof

Abstract

The invention discloses a high performance building cast-in-place concrete and a preparing method thereof. The high performance building cast-in-place concrete is prepared from, by weight, 85-100 parts of sulphoaluminate concrete clinker, 20-30 parts of doped materials, 15-35 parts of granular river sand, 10-15 parts of botanical xylonic acid, 18-25 parts of perlite, 10-20 parts of rubber particles, 20-25 parts of aluminum silicate ceramic fiber, 10-15 parts of anhydrite, 10-20 parts of zeolite powder, 6-9 parts of admixture, 3-7 parts of modifier, 8-15 parts of early strength agent and 10-15 parts of grinding aid. According to the high performance building cast-in-place concrete and the preparing method thereof, effective matching of the sulphoaluminate concrete clinker, the doped materials, the granular river sand, botanical xylonic acid, perlite, the rubber particles, the aluminum silicate ceramic fiber, anhydrite, the zeolite powder, the early strength agent and the grinding aid is adopted, the prepared concrete is strong in crushing resistance and good in crushing resistant effect, qualitative change cannot occur, the production cost is low, the environment pollution can be reduced, and mineral resources are saved; the price is low, the production technology is simple, and the concrete is suitable for scale production.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a high-performance building-in-situ concrete and a preparation method thereof. Background technique [0002] At present, my country's development has been advocating low-carbon environmental protection, energy conservation and emission reduction, and lightweight and thermal insulation of building materials. Among the organic materials commonly used in the building insulation material market, such as polystyrene foam boards, phenolic foam boards, etc., their fire performance is extremely poor and they are easy to burn. The best phenolic foams can only reach B1 level, and their weather resistance is poor Short and expensive to replace. Among inorganic thermal insulation materials: foam glass, foam aluminum, and foam ceramics have high cost prices; although fiber thermal insulation materials such as rock wool are slightly lower in price, they are not hard materials, h...

Problems solved by technology

However, the existing concrete formulations cannot solve the strength and waterproof problems of the joints of prefabricated components well during the splicing and assembly process; although the self-compacting degree of concrete changes when different admixtures are selected, and the relationship between concrete and steel bars The bite force has also been enhanced to a certain extent, but at the same time, the amount of concrete is also increasing, which increases the construction cost, and the occurrence rate of cracks is also relatively high
