Multifunctional activating agent, solid waste based foam concrete and preparation method
The invention relates to the technical field of building materials, and discloses a multifunctional activator, solid waste based foam concrete and a preparation method. The multifunctional activating agent is prepared by rapidly stirring carbonate and/or bicarbonate of alkali metal and sulfate and/or sulfate double salt of alkali metal according to the mass part ratio of 1: 1-1: 2, and positive and negative charges are adsorbed on the surfaces of the carbonate and/or bicarbonate of the alkali metal and the sulfate and/or sulfate double salt of the alkali metal respectively due to mechanical friction; the activating agent not only can activate solid waste, but also has the functions of a foaming agent, a coagulation accelerator, an early strength agent and an expanding agent. The solid waste based foam concrete is prepared from the ordinary Portland cement, the solid waste, the activating agent, the water and the foam stabilizer according to the specified mass parts, and the activating agent is a multifunctional activating agent, so that the foam concrete has the advantages of high early and final strength, shrinkage resistance, good early solid waste activating effect, short demolding time and convenience in rapid construction.
本发明涉及建筑材料技术领域，公开了一种多功能活化剂、固废基泡沫混凝土及制备方法。本发明的多功能活化剂，由碱金属的碳酸盐和/或碳酸氢盐与碱金属的硫酸盐和/或硫酸复盐以质量份数比1:1～1:2，经快速搅拌制得，因为机械摩擦使得碱金属的碳酸盐和/或碳酸氢盐、碱金属的硫酸盐和/或硫酸复盐的表面分别吸附正负电荷，使活化剂不仅可以活化固废，且同时具有发泡剂、促凝剂、早强剂和膨胀剂的功能。本发明的固废基泡沫混凝土，由普通硅酸盐水泥、固废、活化剂、水、以及稳泡剂按照规定的质量份数制得，活化剂是多功能活化剂，使得泡沫混凝土具有早期和最终强度高、抗收缩、早期固废活化效果好、脱模时间短和便于快速施工的优点。
