Light foam concrete for backfilling high-strength corrosion-resistant sunken toilet
The invention discloses high-strength corrosion-resistant light foam concrete for backfilling of a sunken toilet, which is prepared from the following components in parts by weight: 15 to 35 parts of cement, 0.8 to 5.5 parts of superfine fly ash, 0.8 to 5.5 parts of superfine slag powder, 0.8 to 5.5 parts of metakaolin, 0.1 to 0.3 part of vegetable protein agent, 0.1 to 0.3 part of suspending agent, 0.1 to 0.3 part of hydroxypropyl methyl cellulose ether and 0.1 to 0.4 part of foam stabilizer. 0.1 to 0.3 part of polyvinyl alcohol fiber and 0.1 to 0.3 part of calcium formate. The lightweight foam concrete disclosed by the invention can be directly stirred and formed without foaming equipment, so that the construction time can be greatly saved. In addition, by introducing additives with multiple functions, the foamed concrete has the unique functions of high flowability, good uniformity, excellent waterproof effect, corrosion resistance and high later strength.
本发明公开了一种高强度耐腐蚀下沉式卫生间回填用的轻质泡沫混凝土，按重量份数计，由以下组分制成：水泥15‑35份，超细粉煤灰0.8‑5.5份，矿渣微粉0.8‑5.5，偏高岭土0.8‑5.5份，植物蛋白剂0.1‑0.3份，悬浮剂0.1‑0.3份，羟丙基甲基纤维素醚0.1‑0.3份，稳泡剂0.1‑0.4，聚乙烯醇纤维0.1‑0.3份，甲酸钙0.1‑0.3份。本发明所述轻质泡沫混凝土不再需要发泡设备，可以直接搅拌成型，可以大幅度节省施工时间。另外通过引入多种功能的添加剂，使所述发泡混凝土具有流动性大，均匀度好，防水效果优，耐腐蚀，后期强度高的独特功能。
