Foam concrete capable of pumping and chemically foaming and production method of foam concrete

Abstract

The invention discloses foam concrete capable of pumping and chemically foaming and an on-site construction production method. The foam concrete comprises the following materials in parts by weight: 75-500 parts of concrete, 20-120 parts of an active mixing material, 40-300 parts of water, 15-50 parts of an adjusting agent, 30-90 parts of a foaming agent and 2-10 parts of a micro foam agent. The volume weight of the prepared foam concrete is 100-600kg / M<3>; the heat conductivity coefficient of the foam concrete is as low as 0.020W / M.DEG C; the strength of the foam concrete can reach 5Mpa. By virtue of the production method, the advantages of cast-in-situ physical foaming and chemical foaming make an organic combination to form a novel construction method; the production method is relatively high in production efficiency, flexible to operate and relatively wide in application; the foam concrete can be made into high-strength product materials with different shapes; the heat-insulating construction of buildings can be effectively completed with high efficiency and low cost.

Description

Technical field [0001] The invention belongs to the field of pumping chemical foamed foamed concrete and its production technology. It integrates the construction advantages of pumping cast-in-place and the advantages of high chemical self-foaming strength and low water absorption. It can be used to produce various products in the factory and on the construction site. Production method of pouring molding. Background technique [0002] At present, foam concrete is a widely used light-weight thermal insulation material, with its light weight, good thermal insulation performance, and low price, and has become the leading product of environmentally friendly energy-saving materials. Promoting the use of this new type of building material can not only improve building functions, improve construction quality and construction efficiency, and meet the needs of modernization and functionalization of the construction industry, but also effectively utilize existing industrial waste resources...

Problems solved by technology

[0003] The invention patent with the application number 201210125875.5 published on September 12, 2012 discloses a cast-in-place foam concrete and its manufacturing method. The slurry is composed of cement, water, cement foaming agent and admixture. The raw material is cement products, and the internal It is full of closed pore structure, has good affinity with building structure, high strength, durable fire protection, and extensive resources. It is not easy to be uniform, the size of the internal pores is different, the structure is chaotic, and the foaming agent is an organic material, which is not beneficial to the condensation of the cement slurry, resulting in slow condensation, delayed cement hydration, and prone to collapse after pouring.

Its application number is 201010101103.9. The invention patent of polystyrene particle foamed cement composite material mixing and conveying device has the defects of low production mixing efficiency and no automatic control of production.
