Foam concrete and preparation method and application thereof
The invention discloses foam concrete and a preparation method and application thereof. The foam concrete comprises the following components: a cementing material and foam; wherein the cementing material comprises cement, hollow glass beads and water; the foam is prepared by foaming the foaming agent composition; the foaming agent composition comprises surface hydrophilic modified nanoparticles, a surfactant, a conditioning agent and water. The foaming agent composition for pretreating the nanoparticles is adopted for foaming, the obtained foam is stable in performance and low in cost, the foam concrete is prepared from the foam and the hollow glass microspheres, the performance of the foam concrete can be improved, the compressive strength of the foam concrete can be effectively improved, and the market application prospect is wide.
本发明公开了一种泡沫混凝土及其制备方法和应用。这种泡沫混凝土包括以下组分：胶凝材料和泡沫；其中，胶凝材料包括水泥、空心玻璃微珠和水；泡沫由发泡剂组合物发泡制备得到；发泡剂组合物包括表面亲水改性的纳米颗粒、表面活性剂、调节剂和水。本发明采用了对纳米颗粒进行预处理的发泡剂组合物进行发泡，所得的泡沫性能稳定且成本低廉，以此泡沫并利用空心玻璃微球制备泡沫混凝土，可以改善泡沫混凝土的性能，能有效增大泡沫混凝土的抗压强度，市场应用前景广阔。
