Problems solved by technology

However, most of the foamed porous concrete in the prior art has non-closed pores, which leads to the reduction of the strength of the foamed concrete, and the external surface roughness of the concrete after drying is not enough, and the noise insulation rate is low

Abstract

The invention specifically relates to slip-resistant and noise-reducing foam porous concrete and a preparation method thereof and belongs to the technical field of building engineering materials. Theslip-resistant and noise-reducing foam porous concrete and the preparation method thereof provided by the invention have the benefits that foaming is carried out by utilizing an aliphatic alcohol sulfonate air entraining agent combined with sodium carbonate and acetic acid, so that the surface tension of liquid can be effectively reduced; two electron layers are arranged on the surface of a liquidfilm to surround air; air bubbles are closed independently of one another and are not communicated with one another; a foamed cement product is good in permeability resistance; due to the combinationwith vermiculite powder, hydroxyapatite and mullite, the cation exchange capacity is higher, and the cation exchange adsorption capacity is stronger; the slip-resistant and noise-reducing foam porousconcrete is flexural when being heated and expanded, has excellent properties such as thermal insulation, freezing resistance, anti-bacteria, fire prevention, sound absorption, light weight and the like and solves the technical problems that existing foam porous concrete mostly has non-closed porosity, so that the strength of the foamed concrete is reduced; after the concrete is dried, the external surface roughness is insufficient, and the noise isolation rate is low.

Description

technical field [0001] The invention belongs to the technical field of construction engineering materials, and in particular relates to anti-slip and noise-reducing foam porous concrete and a preparation method thereof. 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 contains a large number of closed pores, is light in weight, and can retain heat. The density of foam concrete is small, the density grade is generally 300~1800kg / m³, and the density grade of commonly used foam concrete is 300~1200kg / m 3 , the density is 160kg / m 3 The ultra-light foamed concrete has also been applied in constructio...
