Foam stabilizing and anti-carbonization reinforcing agent for all-solid waste foam concrete as well as preparation method and application thereof
The invention discloses a foam stabilizing and anti-carbonization reinforcing agent for all-solid waste foam concrete as well as a preparation method and application of the foam stabilizing and anti-carbonization reinforcing agent. The preparation method comprises the following steps: taking ettringite, a polycarboxylic acid water reducer, a thickening agent and water as raw materials, firstly obtaining nano ettringite through wet grinding, and then uniformly mixing the nano ettringite with the thickening agent to obtain the foam stabilizing and anti-carbonization reinforcing agent for all-solid waste foam concrete. When the mixing amount of the prepared foam stabilizing and anti-carbonization reinforcing agent is 2.8-8.8%, the 1-hour bleeding rate of foam is smaller than or equal to 10%, the 7-day strength of all-solid-waste foam concrete is improved by 30% or above, the 28-day strength is improved by 20% or above, and the 28-day anti-carbonization capacity is improved by 20% or above.
本发明公开了一种全固废泡沫混凝土用泡沫稳定与抗碳化增强剂及其制备方法和应用。本发明以钙矾石、聚羧酸减水剂、增稠剂、水为原料，先通过湿磨获得纳米钙矾石，再与增稠剂混合均匀，得到全固废泡沫混凝土用泡沫稳定与抗碳化增强剂。本发明制得的泡沫稳定与抗碳化增强剂，掺量2.8‑8.8％时，泡沫1小时泌水率≤10％，全固废泡沫混凝土7天强度提高30％以上，28天强度提高20％以上，28天抗碳化能力提高20％以上。
