Preparation method of low-carbon shrinkage-inhibiting high-alkali activated sand washing tail mud foam concrete
The invention relates to a preparation method of low-carbon shrinkage-inhibiting high-alkali-activated sand washing tail mud foam concrete, which comprises the following steps: mixing and stirring slag, an additive and treated sand washing tail mud, then adding glass fiber and pretreated waste coffee residue, mixing, continuously adding a water glass solution, and stirring, thereby obtaining the foam concrete. Finally, foam prepared from the pretreated foaming agent is added and evenly stirred, and the alkali-activated sand washing tail mud foam concrete is obtained. On one hand, the stability of foam is optimized by microwave treatment of the foaming agent, control of the concentration of the foaming liquid, doping of the admixture and the like, and on the other hand, the strength of the foam concrete is improved by doping of the composite fibers, so that the low-carbon shrinkage-inhibiting high-strength alkali-activated sand washing tailing mud foam concrete is prepared. The foam concrete is green and excellent in performance, so that the foam concrete has a relatively wide popularization prospect.
一种低碳抑缩高强碱激发洗砂尾泥泡沫混凝土的制备方法，首先将矿渣、外加剂和经过处理的洗砂尾泥混合搅拌，接着加入玻璃纤维和预处理废咖啡渣混合，继续加入水玻璃溶液搅拌，最后加入预处理的发泡剂制备的泡沫搅拌均匀获得碱激发洗砂尾泥泡沫混凝土。本发明一方面通过微波处理发泡剂、控制发泡液浓度、掺入外加剂等方式来优化泡沫的稳定性，另一方面通过掺入复合纤维来改善泡沫混凝土强度，进而制备出一种低碳抑缩高强的碱激发洗砂尾泥泡沫混凝土，该泡沫混凝土绿色、优异的性能使其具备较广的推广前景。
