Grass planting brick based on phosphogypsum-based composite cementing material and preparation method of grass planting brick
The invention relates to a grass planting brick based on an ardealite-based composite cementing material and a preparation method thereof.The grass planting brick is prepared from, by mass, 100 parts of the ardealite-based composite cementing material, 0.05-0.3 part of a retarder, 0-0.5 part of a waterproof agent, 0-70 parts of aggregate and 40-70 parts of water, and the ardealite-based composite cementing material is prepared from 70-90 parts of modified ardealite powder, 10-30 parts of blast furnace slag powder and 0-3.5 parts of an alkaline activator; the modified ardealite powder is obtained by calcining and ball-milling ardealite powder. According to the invention, the stockpiling amount of the phosphogypsum can be effectively reduced, the utilization rate of the phosphogypsum is improved, and the modified phosphogypsum powder is calcined and ball-milled, so that leaching of heavy metals and harmful chemical substances can be effectively avoided, and the influence of soluble phosphorus and fluorine is reduced; the preparation method is simple and low in cost, the utilization rate of the ardealite raw material can be increased, and the obtained grass planting brick can meet related standard requirements.
本发明涉及一种基于磷石膏基复合胶凝材料的植草砖及其制备方法，按质量份计，原料包括100份磷石膏基复合胶凝材料、0.05～0.3份缓凝剂、0～0.5份防水剂、0～70份集料和40～70份水，其中，磷石膏基复合胶凝材料包括70～90份改性磷石膏粉、10～30份高炉矿渣粉和0～3.5份碱性激发剂；改性磷石膏粉是由磷石膏粉经过煅烧和球磨得到的。本发明可有效减少磷石膏堆存量，提高其利用率，改性磷石膏粉经过煅烧和球磨，能够有效避免重金属和有害化学物质的浸出，减少可溶性磷和氟的影响；本发明制备方法简单，成本低，能够提高磷石膏原料利用率，所得植草砖能够满足相关标准要求。
