Abstract

The invention discloses a foamed concrete material and a preparation method thereof. The foamed concrete material comprises the following raw materials in parts by weight: 30-45 parts of mountain clay, 20-32 parts of field mud, 10-20 parts of illite, 10-18 parts of coal gangue slag, 15-22 parts of sugarcane waste residues, 1-3 parts of zirconium, 3-8 parts of polymethyl acrylate, 2-8 parts of expanded graphite, 4-9 parts of paraffin, 3-6 parts of magnesium stearate, 2-6 parts of sodium tripolyphosphate, 2-8 parts of tobacco leaf powder and 0.5-2 parts of a foaming agent. The foamed concrete material has a relatively low heat conduction coefficient, is good in thermal insulation property, high in strength, easy in raw material obtaining, lowered in energy consumption and relatively low in production cost, can be massively applied to building engineering, is capable of reducing the construction engineering cost, and is a novel foamed concrete material which can be greatly popularized and applied.

Description

technical field [0001] The invention relates to the construction field, in particular to a foam concrete material 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 current air-entrained concrete generally uses cement as the main cementitious material, and the amount of cement used is extremely large, resulting in high production costs for the board, high energy consumption, and relatively large pollution from the production and transportation of cement; and the existing foamed con...
