The invention discloses a phosphogypsum building block. The building block comprises the following raw materials in parts by weight: 50-70 parts of ardealite, 20-30 parts of slag, 10-20 parts of coalash, 5-10 parts of asbestos, 40-60 parts of water, 1-3 parts of a waterproof agent, 2-4 parts of a water reducing agent, 5-6 parts of a dispersing agent and 3-8 parts of a reinforcing agent. The slagis blast furnace cinder, the fly ash contains crystal mineral mullite, alpha-quartz, calcite, anorthite, calcium silicate, hematite and magnetite, the waterproofing agent is a salt waterproofing agent, and the water reducing agent is a fatty acid water reducing agent and a polycarboxylic acid water reducing agent. According to the phosphogypsum block and preparation method thereof, the product isprepared by mixing and stirring slag, coal lime and asbestos, so that compression resistance and firmness of the formed building block are greatly improved, the breaking strength reaches 6-7 MPa, thecompressive strength is 25-230 MPa, the formed building block can bear a certain weight in the actual use process, and the problem that a traditional phosphogypsum building block can only be used as an inner wall is effectively solved.
本发明公开了磷石膏砌块，包括以下份数的原料：磷石膏50～70份、矿渣20～30份、粉煤灰10～20份、石棉5～10份、水40～60份、防水剂1～3份、减水剂2～4份、分散剂5～6份和增强剂3～8份，所述矿渣为高炉煤渣，粉煤灰含有晶体矿物莫来石、α‑石英、方解石、钙长石、硅酸钙、赤铁矿和磁铁矿，所述防水剂为盐类防水剂，减水剂为脂肪酸系减水剂和聚羧酸系减水剂。该磷石膏砌块及其制备方法，通过放入的矿渣、煤石灰和石棉混合搅拌而成，极大的提高了成型砌块的抗压性和坚固程度抗折强度达到6～7MPa，抗压强度25～230MPa，在实际使用过程中可以使其承受一定的重物，有效的解决了传统的磷石膏砌块只能作为内墙来使用。
