Foam concrete material and preparation method thereof
The invention discloses a foam concrete material and a preparation method thereof, the foam concrete material comprises cement mortar and foam, the cement mortar comprises Portland cement, pulverized coal furnace slag, lime, an alkali activator, a coagulation enhancer, an activator, a waterproof agent and water, and the foam comprises a composite polymer foaming agent, a foam stabilizer, a coagulation enhancer and water. The low-price pulverized coal furnace slag is added to replace fly ash and silica fume in a traditional material, the cost is reduced, the use range of the material is expanded, the concentration of calcium ions in the material is increased by adding lime, the pulverized coal furnace slag contains a large amount of SiO2 with certain activity, the SiO2 reacts with calcium carbonate through alkali excitation to form silicate hydrate, and the silicate hydrate is added to the material. Further, C-S-H is generated, and the strength of the material is further improved; by adopting the composite polymer foaming agent, the foam stabilizing time is long, the water absorption rate of the material is reduced by matching with the waterproof agent, the thermal insulation effect is ensured, and the risk of damage to the material caused by freezing and thawing is reduced.
本发明公开了一种泡沫混凝土材料及其制备方法，其包括水泥砂浆及泡沫，包括水泥砂浆及泡沫，水泥砂浆包括硅酸盐水泥、煤粉炉炉渣、石灰、碱激发剂、促凝增强剂、活化剂、防水剂及水，泡沫包括复合高分子发泡剂、稳泡剂、促凝增强剂及水。通过添加低价的煤粉炉炉渣替代传统材料中的粉煤灰及硅灰，降低了成本，扩大了材料的使用范围，通过添加石灰以增加材料中钙离子的浓度，煤粉炉炉渣含有大量的有一定活性的SiO2，通过碱激发，它和碳酸钙反应形成硅酸盐水化物，进而生成C‑S‑H，进一步提高了材料的强度；通过采用复高分子发泡剂，使泡沫稳定时间长，与防水剂配合使用降低了材料的吸水率，保证了保温效果，降低了冻融对材料破坏的风险。
