Phosphogypsum solid waste aerated concrete and preparation method thereof
The invention provides ardealite solid waste aerated concrete and a preparation method thereof. The ardealite solid waste aerated concrete is prepared from the following components in parts by mass: 5-9 parts of cement, 10-18 parts of lime, 45-60 parts of ardealite, 9-12 parts of fly ash, 9-12 parts of quartz sand tailings, 0.8-1.2 parts of a composite early strength agent, 1-2 parts of bentonite, 0.5-1 part of limestone powder, 0.15 part of a foaming agent, 0.2-0.3 part of polyacrylonitrile fiber and 2-3 parts of wollastonite, wherein the composite early strength agent is a mixture of sodium carbonate and calcium sulphoaluminate cement. The B05-grade ardealite solid waste aerated concrete block is prepared through optimal design of a formula, 70% or above of solid waste mainly containing ardealite is utilized on the premise that the requirements for building performance, application parameters and the like are met, the cost, comprehensive energy consumption, comprehensive carbon emission and the like of the block are remarkably reduced, and the production cost is reduced. And the prepared aerated concrete block is uniform in pore structure and relatively high in closed porosity, so that the comprehensive properties such as strength, volume stability and freezing resistance of the aerated concrete are improved.
本发明提供了一种磷石膏固废加气混凝土及其制备方法，包括按质量份数计的如下组分：水泥5～9份，石灰10～18份，磷石膏45～60份，粉煤灰9～12份，石英砂尾矿9～12份，复合早强剂0.8～1.2份，膨润土1～2份，石灰石粉0.5～1份，发泡剂0.15份，聚丙烯腈纤维0.2～0.3份，硅灰石2～3份；其中，所述复合早强剂为碳酸钠和硫铝酸钙水泥的混合物。本发明通过配方的优化设计，制得B05级的磷石膏固废加气混凝土砌块，在满足建筑性能及应用参数等要求上，利用磷石膏为主的70％以上固废，显著降低砌块成本、综合能耗、综合碳排放量等，并且制得的加气混凝土砌块的气孔结构均匀且闭气孔率较高，从而提高了加气混凝土的强度、体积稳定性、抗冻性等综合性能。
