Foam concrete doped with pumice and preparation method thereof
The invention relates to the technical field of concrete, in particular to a method for preparing light high-strength foam concrete, which is characterized in that the foam concrete comprises the following raw materials in parts by weight: 20-25 parts of water, 50-60 parts of cement, 20-30 parts of fly ash, 12-18 parts of silica fume, 3-5 parts of nano silicon dioxide, 1-3 parts of lime powder, 90-110 parts of quartz sand and 1-1.5 parts of water reducing agent. The building material comprises the following components in parts by volume: 15-25 parts of quartz sand, 10-20 parts of expanded perlite, 20-30 parts of 1-3mm aggregate pumice stone, 40-60 parts of 3-5mm aggregate pumice stone and 45-60 parts of foam. Wherein the water reducing agent is a polycarboxylic acid water reducing agent. The novel pumice-doped foam concrete is researched and developed, high strength is achieved on the premise that the pumice-doped foam concrete is light, waste utilization can be improved, and contribution is made to improvement of engineering economic benefits and green sustainable development.
本发明专利涉及混凝土技术领域，尤其涉及一种制备轻质高强泡沫混凝土方法，其技术方案要点是，按重量份数计算，这种泡沫混凝土原料包括：水20‑25份，水泥50‑60份，粉煤灰20‑30份，硅灰12‑18份，纳米二氧化硅3‑5份，石灰粉1‑3份，石英砂90‑110份，减水剂1‑1.5份；按体积份数计算，石英砂15‑25份，膨胀珍珠岩10‑20份，1‑3mm集配浮石20‑30份，3‑5mm集配浮石40‑60份，泡沫45‑60份。其中，减水剂采用聚羧酸系减水剂。本发明研发了一种新型掺浮石泡沫混凝土，在较为轻质的前提的下实现较高强度，又能提高废弃物利用，为提高工程经济效益和绿色可持续发展做出贡献。
