Abstract

The invention discloses a high-performance foam concrete which comprises the following raw materials: cement, river sand, lime, a composite foaming agent, fly ash, metakaolin, expanded perlite, lignin fiber, polypropylene glycol, hydroxymethyl propyl cellulose, styrene-acrylic emulsion, 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, a water-reducing agent, an early strength agent and water; the composite foaming agent comprises the following raw materials: tea saponin, lauryl sodium sulfate, sodium fatty alcohol polyoxyethylene ether sulfonate, 1,4-butanediol, triethanolamine, soybean oil, sodium hydroxide, zeolite powder, polyacrylate resin and water. The high-performance foam concrete disclosed by the invention is good in pumpability in the construction process, high in compressive strength and good in durability.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a high-performance 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. Foamed concrete material is widely used in various fields because of its numerous small independent, evenly distributed, and closed pore structures, so it has the characteristics of light weight, high strength, heat insulation, waterproof, fireproof, and earthquake resistance. However, due to the large number of bubbles in the foam concrete itself, its strength is often not ideal, and further improvement is needed. Contents of the in...
