Foamed light soil and preparation method thereof
The invention discloses foamed light soil and a preparation method thereof, and relates to the technical field of green building materials. The foamed light soil comprises the following components byweight: 200-220 parts of cement, 130-150 parts of fly ash, 5-10 parts of silica gel powder, 2-6 parts of a retarder, 30-35 parts of a foaming liquid, and 220-240 parts of water. The preparation methodof the foamed light soil comprises the following steps: S1, preparing a foamed material: introducing compressed air into a foaming liquid by utilizing an air compressor to form the foamedmaterial; S2, preparing a cementing material: uniformly mixing and dispersing cement, fly ash, silica gel powder, metakaolin and apolymer/nano montmorillonite composite material, adding a coagulant and water, anduniformly mixing to obtain the cement cementing material; S3, mixing: mixing the foamed material obtained in the step S1 with the cementing material obtained in the step S2, and uniformly stirring toobtain the foamed light soil. The invention has the technical effects of high compressive strength, excellent mechanical properties and stable long-term performance.
本发明公开了一种泡沫轻质土及其制备方法，涉及绿色建筑材料的技术领域，按重量份数计，包括以下组分：水泥200‑220份、粉煤灰130‑150份、硅胶粉5‑10份、缓凝剂2‑6份、发泡液30‑35份、水220‑240份。该泡沫轻质土的制备方法包括以下步骤：S1.发泡料制备：利用空气压缩机将压缩空气通入发泡液中，形成泡沫发泡料；S2.胶凝料制备：将水泥、粉煤灰、硅胶粉、偏高岭土和聚合物/纳米蒙脱土复合材料混合分散均匀，加入混凝剂和水，混合均匀得到水泥胶凝料；S3.混料：将S1步骤得到的泡沫发泡料与S2步骤得到的水泥胶凝料混合并搅拌均匀，得到泡沫轻质土。本发明具有抗压强度高、力学性能优异且长期性能稳定的技术效果。
