Abstract

The invention discloses foam concrete. The foam concrete comprises following raw materials in parts by mass according to a formula: 210-300 parts of cement, 1.0-1.5 parts of a water reducing agent, 5.1-5.5 parts of an early strength agent, 2.1-2.9 parts of a coagulant, 1.7-3.4 parts of fibers, 12-20 parts of a chemical foaming agent, 0-90 parts of superfine slag powder and 100-160 parts of water, wherein the superfine slag powder is formed by aluminosilicate glass particles smaller than 15 mu m, and the specific surface area is 450-500 m<2>*kg<-1>. The compressive strength of the foam concrete is improved on the premise that the foam concrete keeps low density.

Description

technical field [0001] The present invention relates to a technical field of building materials, more specifically, it relates to a foam concrete. Background technique [0002] Foamed concrete is made of foaming agent aqueous solution by physical method, and then the foam is added to the slurry made of cement, aggregate, admixture, admixture and water, etc. After mixing, pouring, natural or Porous concrete made with steam curing. It contains a large number of closed voids, so it shows good physical properties and use functions, such as light weight, heat preservation, heat insulation, moisture resistance, sound insulation, etc. Foam concrete has a huge market in wall and roof thermal insulation projects, lightweight concrete components and products, building floor heating systems, large tunnels, high-grade highways and subway backfill projects, building lightweight cushions, and sound-absorbing barriers. demand and broad prospects for promotion. [0003] However, the poro...
