Self-breathing foam light soil based on phosphogypsum and preparation method of self-breathing foam light soil
The invention discloses self-breathing foam light soil based on phosphogypsum and a preparation method thereof.The self-breathing foam light soil comprises a framework, a first air hole group and a second air hole group, first air holes are communicated with second air holes around the first air holes through communicating holes in the framework, and the second air holes are communicated with the second air holes around the second air holes through communicating holes in the framework; the diameter of the first air hole is larger than that of the second air hole; the method comprises the following steps: preparing a first bubble group and a second bubble group, stirring ardealite mucilage, adding cement and mineral powder to prepare mixed mucilage, uniformly mixing the mixed mucilage with the bubble groups, puncturing a bubble liquid film by needle-like ettringite generated by a hydration reaction to enable bubbles to be communicated, and further performing the hydration reaction on the mucilage and curing to form a framework. The self-breathing foam light soil disclosed by the invention has excellent water permeability and water-retaining property, utilizes a large amount of solid waste materials, and is low-carbon, environment-friendly and good in economical efficiency.
本发明公开了一种基于磷石膏的自呼吸泡沫轻质土及其制备方法，包括骨架以及第一气孔群、第二气孔群，第一气孔与其周边的第二气孔通过骨架中的连通孔连通，第二气孔与其周边的第二气孔通过骨架中的连通孔连通，第一气孔的直径大于第二气孔直径；步骤包括制备第一气泡群、第二气泡群，拌制磷石膏胶浆，加入水泥、矿粉制成混合胶浆，再与气泡群混合均匀，水化反应产生的针状钙矾石刺破气泡液膜，使气泡间连通，胶浆进一步水化反应固化后形成骨架。本发明的自呼吸泡沫轻质土兼具优良的透水性和保水性，且大量利用固废材料，低碳环保，经济性好。
