Construction waste foam concrete as well as preparation method and application thereof
The invention discloses construction waste foam concrete as well as a preparation method and application thereof, and relates to the technical field of building materials. Specifically, the raw materials comprise construction waste aggregate, a cementing material and an additive; the construction waste aggregate comprises concrete and broken brick slag; the cementing material comprises PO42.5 Portland cement, calcium aluminate cement, lime and gypsum; the additives comprise sodium sulfate, water glass, mineral powder, glass fiber, sodium hydroxide, a foam stabilizer and aluminum powder; the ratio of water to material is 0.35. The preparation process comprises the following steps: mixing the components except the sodium hydroxide and the water glass to obtain a mixture; sodium hydroxide and water glass are dissolved in water to obtain a mixed solution, the mixed solution is added into the mixture to obtain slurry, and the slurry is cured and formed. The construction waste foam concrete disclosed by the invention has the characteristics of small heat conductivity coefficient, relatively high strength and fast solidification, and provides reference for producing regenerated building materials meeting the application requirements of prefabricated buildings while realizing efficient utilization of the construction waste.
本发明公开了一种建筑垃圾泡沫混凝土及其制备方法和应用，涉及建材技术领域。具体公开了：原料包括建筑垃圾骨料、胶凝材料和外加料；建筑垃圾骨料包括混凝土和碎砖渣；胶凝材料包括PO42.5硅酸盐水泥、铝酸钙水泥、石灰和石膏；外加料包括硫酸钠、水玻璃、矿粉、玻璃纤维、氢氧化钠、稳泡剂和铝粉；水料比为0.35。制备过程：将除氢氧化钠和水玻璃外的组分混合，得混合料；将氢氧化钠和水玻璃溶于水，得混合液，将混合液加入混合料中，得到浆料，进行养护成型即可。本发明的建筑垃圾泡沫混凝土具有导热系数小、强度较大、凝固快的特点，在实现建筑垃圾高效利用的同时，为生产满足装配式建筑应用要求的再生建材提供参考。
