Phosphogypsum-based waterproof mortar and preparation method thereof
The invention relates to the technical field of preparation of waterproof mortar in civil engineering materials, and discloses ardealite-based waterproof mortar and a preparation method thereof. The waterproof mortar is prepared from the following components in parts by weight: 41.6 to 60 parts of phosphogypsum, 4.4 to 6 parts of building gypsum, 30 to 50 parts of slag, 4 parts of cement, 0.15 to 0.30 part of K2SO4, 33 to 39 parts of water, 150 to 225 parts of fine sand, 0 to 5 parts of latex powder, 0 to 4.5 parts of tung oil or 0 to 1.5 parts of calcium stearate, 0.07 to 0.13 part of water reducing agent and 0 to 0.15 part of defoaming agent, and the water-binder ratio is 0.33 to 0.39. The calcined phosphogypsum is used as a base material, cement, slag, lime and other materials are added to prepare the waterproof mortar with an excellent waterproof effect, and tung oil, calcium stearate and other waterproof agents are used to further enhance the waterproof performance of the waterproof mortar, so that the limitation that gypsum can only be used as an air hardening cementing material is broken through.
本发明涉及土木工程材料中防水砂浆制备技术领域，公开了一种磷石膏基防水砂浆及其制备方法，该防水砂浆包括如下重量份的组分：41.6‑60份磷石膏、4.4‑6份建筑石膏、30‑50份矿渣、4份水泥、0.15‑0.30份K2SO4、水33‑39份、细砂150‑225份、乳胶粉0‑5份、桐油0‑4.5份或硬脂酸钙0‑1.5份、减水剂0.07‑0.13份与消泡剂0‑0.15份，其中，水胶比为0.33‑0.39。本发明通过以煅烧后的磷石膏为基料，添加水泥、矿渣、石灰等材料制作防水效果优异的防水砂浆，并使用桐油和硬脂酸钙等防水剂进一步增强其防水性能，打破了石膏只能作为气硬性胶凝材料的限制。
