Non-autoclaved high-strength foam concrete and preparation method thereof
The invention provides a non-autoclaved high-strength foam concrete and a preparation method thereof, and belongs to the technical field of building materials. The foam concrete comprises, by mass, 60-80% of a cementing material, 15-25% of water, 0.01-0.1% of a foaming agent, 0.05-0.5% of reinforced fibers and 0.1-0.3% of a water reducing agent. The cementing material is composed of cement, steel slag and fly ash or superfine slag powder, the foaming agent is a composite concrete foaming agent, the reinforced fibers are polypropylene fibers or alkali-resistant glass fibers or basalt fibers or lignin fibers with the length of 3-12 mm, and the water reducing agent is a polycarboxylic acid type high-efficiency water reducing agent. The mechanical strength and heat insulation effect of the prepared foam concrete are better than those of existing foam concrete with the same density; and the foam concrete prepared by the invention does not need autoclaved curing, and can reach relatively high strength after being naturally stacked for three days.
本发明提供一种免蒸压的高强泡沫混凝土及其制备方法，属于建筑材料技术领域。本发明泡沫混凝土的组成及其质量百分数是：胶凝材料60～80，水15～25，发泡剂0.01～0.1，增强纤维0.05～0.5，减水剂0.1～0.3。胶凝材料由水泥、钢渣和粉煤灰或矿渣微粉组成，发泡剂为复合型混凝土发泡剂，增强纤维为3～12mm长的聚丙烯纤维或耐碱玻璃纤维或玄武岩纤维或木质素纤维，减水剂为聚羧酸系高效减水剂。本发明所制备的泡沫混凝土的力学强度、隔热效果比已有的相同密度的泡沫混凝土更好；本发明所制备的泡沫混凝土无需蒸压养护，自然堆放三天就能达到较高强度。
