Multi-source solid waste-based foam light soil as well as preparation method and application thereof
The invention discloses multi-source solid waste-based foam light soil as well as a preparation method and application thereof, and belongs to the technical field of roadbed engineering. The building material is prepared from the following components in parts by mass: 14 to 22 parts of a first admixture, 1 to 11 parts of red mud, 2 to 11 parts of gypsum, 1 to 17 parts of a second admixture, 0.1 to 0.5 part of fibers, 0.05 to 0.3 part of nanofibers, 5 to 20 parts of steel slag powder, 0.1 to 3 parts of an expanding agent, 20 to 46 parts of blast furnace slag, 8 to 23 parts of metakaolin, 0.05 to 0.2 part of a foam stabilizer, 3 to 6 parts of a foaming agent and 20 to 31 parts of water, the first admixture is selected from at least one of silty soil, saw mud or recycled powder; the second admixture is selected from at least one of fly ash or decarburized coal gangue powder. The foam light soil is high in bearing capacity, good in durability, high in shrinkage resistance, good in water stability and low in cost, is used as roadbed filler, and reduces vertical pressure on soft foundations on the basis of meeting roadbed performance requirements.
本发明公开了一种多源固废基泡沫轻质土及其制备方法与应用，属于路基工程技术领域。按质量份数计，其包括：第一掺合料14‑22份，赤泥1‑11份，石膏2‑11份，第二掺合料1‑17份，纤维0.1‑0.5份，纳米纤维0.05‑0.3份，钢渣粉5‑20份，膨胀剂0.1‑3份，高炉矿渣20‑46份，偏高岭土8‑23份，稳泡剂0.05‑0.2份，发泡剂3‑6份，水20‑31份；第一掺合料选自粉质土、锯泥或回收粉中的至少一种；第二掺合料选自粉煤灰或脱碳煤矸石粉中的至少一种。该泡沫轻质土承载能力强、耐久性好、抗收缩能力强、水稳定性好、成本低，用作路基填料，在满足路基性能要求的基础上减少对软弱地基的竖向压力。
