High-dosage composite stone powder foam concrete and preparation method thereof
The invention belongs to the technical field of solid waste utilization and foam concrete preparation, and particularly relates to high-dosage composite stone powder foam concrete and a preparation method thereof.The high-dosage composite stone powder foam concrete is prepared from, by weight, 10-20 parts of coarse stone powder, 30-40 parts of fine stone powder, 2-3 parts of superfine stone powder, 30-40 parts of cement, 0.16-0.2 part of foaming agent, 0.4-1 part of water reducing agent, 0.8-1.5 parts of coagulation accelerator and 25-35 parts of water; the specific surface area of the coarse stone powder is 50-300m < 2 >/kg; the specific surface area of the fine stone powder is 300-600m < 2 >/kg; the specific surface area of the superfine stone powder is 5000-9000 m < 2 >/kg, and the prepared high-mixing-amount composite stone powder foam concrete is high in stone powder mixing amount, stable in mechanical property, green, economical and good in market popularization prospect.
本发明属于固废利用和泡沫混凝土制备技术领域，具体涉及一种高掺量复合石粉泡沫混凝土及其制备方法，按重量份计，所述泡沫混凝土制备材料为：粗石粉10~20份、细石粉30~40份、超细石粉2~3份、水泥30~40份、泡沫剂0.16~0.2份、减水剂0.4~1份、促凝剂0.8~1.5份和水25~35份；所述粗石粉比表面积在50~300m2/kg；所述细石粉比表面积在300~600m2/kg；所述超细石粉比表面积在5000~9000m2/kg，本发明制备出的高掺量复合石粉泡沫混凝土，该泡沫混凝土石粉掺量高、力学性能稳定且绿色经济，具备较好的市场推广前景。
