Embodiment 1

[0022] A foam concrete main material, comprising the following raw materials in weight percentage: 10% cement clinker, 85% admixture, 0.1% quicklime, 4% glass fiber, 0.1% dispersible latex powder, 0.3% coagulant , 0.2% water reducer and 0.3% foam stabilizer, wherein the cement clinker is Portland cement clinker, the admixture is fly ash, the coagulation accelerator is lithium carbonate, and the reducer The water agent is sodium lignosulfonate, and the foam stabilizer is polyvinyl alcohol.

[0023] Adopt above-mentioned foam concrete main material to prepare foam concrete, preparation method comprises the following steps:

[0024] (1) Slurry configuration: cement clinker, admixture, quicklime, glass fiber, dispersible latex powder, coagulant and water reducing agent are weighed according to the design ratio, and dry mixed evenly, and then added with foam 50% water of the total mass of the concrete main material is stirred evenly to obtain a slurry;

[0025] (2) Preparation of...

Embodiment 2

[0028] A foam concrete main material, including the following raw materials in weight percentage: 40% cement clinker, 50% admixture, 6.3% quicklime, 2% glass fiber, 1% dispersible latex powder, 0.3% coagulant , 0.3% water reducer and 0.1% foam stabilizer, wherein the cement clinker is sulphoaluminate cement clinker, the admixture is slag, the coagulation accelerator is gypsum, and the water reducer It is calcium lignosulfonate, and the foam stabilizer is sodium α-alkenyl sulfonate.

[0029] The preparation method of the foamed concrete in Example 2 is basically the same as that of the foamed concrete in Example 1, except that the foaming agent added in Example 2 is purchased from Luoyang Tongrun Information Technology Co., Ltd., and the model is TRZQ-702 , others are identical with embodiment 1.

Abstract

The invention discloses a foam concrete main material, which is made of the following raw materials in weight percentage: 10%-46% of cement clinker, 50%-85% of admixture, 0-10% of quicklime, and 2%-6% of glass fiber %, dispersible latex powder 0‑1%, coagulant 0.3%‑0.5%, water reducing agent 0.2%‑0.4% and foam stabilizer 0.1%‑1%. The main material of the foam concrete provided by the invention solves the problem that the foam concrete mainly uses cement as the main material at present, so that the quality of the obtained foam concrete is unstable and the strength is not enough.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foam concrete main material. Background technique [0002] Foamed concrete is made of foaming agent solution by mechanical means, and then the foam is mixed into siliceous materials, calcium materials, and various admixtures and water mixtures, stirred evenly and poured into various required concrete. Specifications, cured lightweight concrete with a large number of closed pores. Most of the existing foam concrete materials are mainly cement, and the cement is directly used as the cementing material, and the mass percentage in the concrete can account for 70-85%. It is made by mixing and curing with foaming agent. [0003] The Chinese patent with the application number 2016101764882 discloses a foam concrete, which is first made of water, cement, anti-crack fiber, anti-crack agent, fly ash and redispersible latex powder to make an intermediate slurry, wherein, by weight rati...
