Abstract

The invention discloses thermal insulation anti-cracking foam concrete. The thermal insulation anti-cracking foam concrete comprises the following raw materials: cement, glass beads, limestone flour, a composite foaming agent, metakaolin, basalt fiber, lignin fiber, alpha-methyl-2,4-pentanediol, vinyl acetate-ethylene copolymer, a water reducer, an early strength agent, a pumping aid and water, wherein the composite foaming agent contains the following raw materials: N-lauroyl-L-sodium glutamate, sodium dodecyl benzene sulfonate, fatty alcohol-polyoxyethylene ether, oleic acid, triethanolamine, lauryl diethanolamine, zeolite powder and water. The thermal insulation anti-cracking foam concrete has high strength, a good anti-cracking effect and excellent thermal insulation performance.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a thermal insulation and anti-cracking foam concrete. Background technique [0002] Foamed concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then go through the pumping system of the foaming machine for cast-in-place construction or mold molding. A new type of lightweight thermal insulation material containing a large number of closed pores formed by curing. It is a member of the concrete family, with low density, light weight, thermal insulation, sound insulation, and earthquake resistance. It is a new type of building material and can be applied to retaining walls, construction of sports fields and track and field tracks, sandwich components, as Composite wall panels, pipeline backfill, lean concrete fill, roof slopes, support for storage tank feet, etc. However, foa...
