Lightweight foam concrete
The invention discloses lightweight foam concrete, and belongs to the technical field of lightweight concrete. The foamed concrete is prepared from the following raw materials in parts by weight: 100-120 parts of cement, 10-20 parts of fly ash, 5-10 parts of standard sand, 1-3 parts of a foam stabilizer, 1-3 parts of a water reducing agent, 3-5 parts of a modified animal protein foaming agent, 0.5-1.5 parts of polymer fibers and 0.8-1.2 parts of organic rubber powder. The foam concrete prepared by preparing the modified animal protein foaming agent and adding the fly ash, the butadiene-acrylonitrile rubber powder and other materials together has low dry density and heat conductivity coefficient, high sound absorption coefficient and good heat insulation and sound insulation effects under the condition that the compressive strength meets the building requirements, and the comprehensive performance is synchronously improved. And the preparation technology is simple, the raw material cost is low, the technological process is green, safe and pollution-free, and good economic benefits and social benefits are achieved.
本发明公开一种轻质泡沫混凝土，属于轻质混凝土技术领域。本发明发泡混凝土包括以下重量份的原料制备而成：水泥100‑120份、粉煤灰10‑20份、标准砂5‑10份、稳泡剂1‑3份、减水剂1‑3份、改性动物蛋白发泡剂3‑5份、聚合纤维0.5‑1.5份、有机胶粉0.8‑1.2份。本发明制备改性动物蛋白发泡剂，添加粉煤灰、丁腈胶粉等材料，共同制备得到的泡沫混凝土，抗压强度满足建筑需求的情况下，具有较低的干密度和导热系数，较高的吸声系数，隔热隔音效果良好，综合性能得到同步提升。且制备工艺简单，原料成本低，工艺过程绿色安全无污染，具有良好的经济效益和社会效益。
