Foam lightweight concrete, preparation method thereof and foundation structure
The invention belongs to the technical field of constructional engineering, and provides foamed lightweight concrete, a preparation method thereof and a foundation structure, the foamed lightweight concrete comprises the following components by weight: 150-200 parts of cement; 100 to 250 parts of fly ash; 30 to 55 parts of silica fume; 10 to 25 parts of organic silicon resin; 2-5 parts of mixed fiber; 2.5-4 parts of a foaming agent; 240 to 320 parts of water; wherein the mixed fibers comprise at least two of modified basalt fibers, polypropylene fibers, alkali-resistant glass fibers, polyvinyl alcohol fibers and regenerated bamboo fibers. The lightweight concrete is light in weight, uniform and stable in texture, good in compression resistance and fracture resistance, high in composite strength and good in durability; the method is suitable for unstable foundations such as side slopes and terraces, the self weight can be reduced, the structural strength is high, and the safety and stability of the foundations can be well guaranteed.
本发明属于建筑工程技术领域，提供了一种泡沫轻质混凝土及其制备方法和地基结构，该泡沫轻质混凝土包括按重量份计的如下组分：水泥150~200份；粉煤灰100~250份；硅灰30~55份；有机硅树脂10~25份；混合纤维2~5份；发泡剂2.5~4份；水240~320份；其中，所述混合纤维包括改性玄武岩纤维、聚丙烯纤维、耐碱玻璃纤维、聚乙烯醇纤维、再生竹纤维中的至少两种。该轻质混凝土质量轻，质地均匀、稳定，抗压、抗折性能好，复合强度高和耐久性好；适用于边坡及阶地等不稳定地基，可减轻自重，结构强度高，能很好的保证地基的安全性和稳定性。
