Foam concrete and preparation method thereof
The invention discloses foam concrete and a preparation method thereof, the foam concrete comprises gel material slurry, a water reducing agent and foam, the volume ratio of the foam to the gel material is 9: 1, the water-binder ratio of the gel material slurry is 0.3, the dilution ratio of a foaming agent in the foam is 30 times, the mixing amount of the water reducing agent is 2% of the mixing amount of the cementing material, the mass ratio of the fly ash in the cementing material is 40%-60%, the mass ratio of the cement in the cementing material is 40%-60%, and the foaming agent is an animal foaming agent; The concrete comprises the following components in parts by weight: 440-660 parts of the cement, 440-660 parts of the fly ash, 330 parts of water for cement paste, 22 parts of the water reducing agent, 16.2 parts of the foaming agent and 469.8 parts of water for the foaming agent. The foam concrete provided by the invention has excellent thermal insulation property and mechanical property, solves the problem that the dry density and compressive strength of the foam concrete are mutually restricted, and lays a foundation for the development of the foam concrete.
本发明公开了一种泡沫混凝土及其制备方法，所述泡沫混凝土包括凝胶材料料浆、减水剂及泡沫，所述泡沫与所述胶凝材料的体积比为9:1，所述凝胶材料料浆的水胶比为0.3，所述泡沫中泡沫剂的稀释倍数为30倍，所述减水剂的掺量为胶凝材料掺量的2％，所述胶凝材料中粉煤灰的质量比为40％‑60％，水泥的质量比为40％‑60％，泡沫剂选用动物泡沫剂；按照重量份计，包括以下各组分：水泥440‑660份、粉煤灰440‑660份、水泥浆用水330份、减水剂22份、泡沫剂16.2份、泡沫剂用水469.8份。本发明所述的泡沫混凝土兼具了优良的保温性和力学性能，解决了泡沫混凝土干密度与抗压强度相互制约的问题，为泡沫混凝土的发展奠定了基础。
