Phosphogypsum hardening agent and preparation method and application thereof
The invention relates to the technical field of harmless treatment of solid wastes, in particular to a phosphogypsum hardening agent as well as a preparation method and application thereof. The ardealite hardening agent provided by the invention is prepared from the following preparation raw materials in parts by weight: 1580 to 1780 parts of ardealite, 10 to 30 parts of a modifier, 100 to 130 parts of an active mineral admixture, 100 to 140 parts of cement, 15 to 40 parts of metakaolin, 10 to 35 parts of coal gangue slag, 5 to 10 parts of an early strength agent and 50 to 80 parts of water. The ardealite hardener can effectively enhance the early strength of ardealite, reduce the initial setting time and the final setting time of the hardened ardealite, improve the durability, the wear corrosion resistance and the erosion resistance of a material after ardealite hardening, and meanwhile, the material after ardealite hardening can meet the environmental quality standards of soil, surface water and underground water, and has a good application prospect. The problem that a large amount of ardealite is difficult to treat and utilize due to poor ardealite performance at present is solved.
本发明涉及固废无害化处理技术领域，尤其涉及一种磷石膏硬化剂及其制备方法和应用。本发明提供的磷石膏硬化剂，以重量份数计，包括以下制备原料：磷石膏1580～1780份，改性剂10～30份，活性矿物掺合料100～130份，水泥100～140份，偏高岭土15～40份，煤矸石炉渣10～35份，早强剂5～10份和水50～80份。本发明所述的磷石膏硬化剂能够有效的增强磷石膏的早期强度，减少硬化磷石膏的初凝和终凝时间，提高磷石膏硬化后材料的耐久性、耐磨腐蚀性、抗冲刷性，同时，磷石膏硬化后材料能够满足土壤、地表水和地下水环境质量标准，解决目前因磷石膏性能差造成的磷石膏大量处置利用难的问题。
