Foam concrete as well as preparation method and application thereof
The invention discloses foam concrete as well as a preparation method and application thereof, and belongs to the technical field of concrete materials. The foam concrete provided by the invention is prepared from the following raw materials in parts by mass: 500 to 1200 parts of cementing material, 10 to 800 parts of superfine filler, 1 to 30 parts of polyvinyl alcohol fiber and 100 to 800 parts of water, the raw materials further comprise nano-foam, and the volume ratio of the nano-foam to the cementing material is (0.05-30): 1; and the particle size range of the superfine filling material is 1-50 [mu] m. By adding the nano-foam, the cementing material, the superfine filler and the polyvinyl alcohol fiber, the hydration time of the foam concrete is effectively shortened, the compressive strength and the breaking strength of the foam concrete are improved, meanwhile, the percentage of close area in the foam concrete is increased, the water absorption rate and the thermal conductivity of the foam concrete are effectively reduced, and the foam concrete has a good application prospect. The foam concrete with low volume weight and high strength is obtained.
本发明公开了一种泡沫混凝土及其制备方法和应用，属于混凝土材料技术领域。本发明提供的泡沫混凝土包括以下原料质量份数的原料：500～1200份胶凝材料、10～800份超细填充料、1～30份聚乙烯醇纤维、100～800份水；所述原料还包括纳米泡沫，所述纳米泡沫与所述胶凝材料的体积比为(0.05～30)：1；所述超细填充料粒径范围为1～50μm。本发明通过加入纳米泡沫、胶凝材料、超细填充料和聚乙烯醇纤维，有效地加快了泡沫混凝土的水化时间，提升了泡沫混凝土的抗压和抗折强度，同时也增加了泡沫混凝土中的闭孔率，有效降低了泡沫混凝土的吸水率以及导热率，得到了兼具低容重和高强度的泡沫混凝土。
