Lead-zinc tailing single-component geopolymer masonry mortar and preparation method thereof
The invention provides lead-zinc tailing single-component geopolymer masonry mortar and a preparation method thereof. The lead-zinc tailing single-component geopolymer masonry mortar is prepared from the following components in parts by weight: 30 to 50 parts of lead-zinc tailings, 50 to 70 parts of mineral powder, 15 to 30 parts of sodium hydroxide, 250 to 450 parts of fine aggregate and 50 to 100 parts of water. The invention relates to a preparation method of lead-zinc tailing single-component geopolymer masonry mortar, which comprises the following steps of: carrying out mix proportion design on alkali heat activated lead-zinc tailings and powder to prepare the masonry mortar of which the strength and the working performance meet the engineering practical application requirements and the price is relatively low. Compared with ordinary Portland cement, the carbon emission of the precursor used in the preparation process can be reduced by 82%, and the preparation process has a very good popularization prospect.
本发明提供一种铅锌尾矿单组分地聚物砌筑砂浆及其制备方法。其中，所述铅锌尾矿单组分地聚物砌筑砂浆由以下成分及含量组成(按重量份数计)：30‑50份铅锌尾矿，50‑70份矿粉，15‑30份氢氧化钠，250‑450份细骨料和50‑100份水。一种铅锌尾矿单组分地聚物砌筑砂浆的制备方法，将碱热活化后的铅锌尾矿和粉料，进行配合比设计，配制出强度和工作性能满足工程实际应用要求并且价格相对低廉的砌筑砂浆。相较于普通硅酸盐水泥，该制备工艺使用的前驱体的碳排放可以降低82％，十分具有推广前景。
