Calcium silicate board prepared from solid waste and preparation method thereof
The invention belongs to the technical field of building materials, and particularly provides a calcium silicate board prepared from solid waste, which comprises 19-40% of cement, 0-27% of quartz sand, 24-55% of desulfurized gypsum, 6-15% of fly ash, 3-5% of inorganic gap filling material and 6-10% of reinforced fiber. According to the calcium silicate board provided by the invention, the desulfurized gypsum and the fly ash are taken as main raw materials, and are matched with the cement, the high-activity inorganic gap filling material, the reinforced fibers and the like, so that the calcium silicate board meeting the national standard is produced and prepared, and the product not only can reduce environmental pollution caused by discharge of the desulfurized gypsum and the fly ash, but also can reduce the operating cost of an enterprise. The invention further provides a preparation method of the calcium silicate board, compared with an existing industrial calcium silicate board, the requirement for a maintenance system is low, carbon emission can be reduced, an existing production process does not need to be changed, and the prepared product is excellent in performance and considerable in economic benefit.
本发明属建筑材料技术领域，具体提供了一种利用固废制备的硅酸钙板，包括：19‑40％的水泥，0‑27％的石英砂，24‑55％的脱硫石膏，6‑15％的粉煤灰，3‑5％的无机填隙材料，6‑10％的增强纤维。本发明提供的硅酸钙板以脱硫石膏和粉煤灰为主要原料，并配以水泥、高活性无机填隙材料和增强纤维等，生产制备符合国家标准的硅酸钙板，产品不仅能减少脱硫石膏和粉煤灰排放对环境的污染，还能够降低企业的经营成本。本发明还提供了该硅酸钙板的制备方法，相对现有工业生产的硅酸钙板而言，养护制度要求低，能够降低碳排放，且不需改变现行的生产工艺，制得的产品性能优良，经济效益可观。
