Gypsum plastering mortar based on gold tailings and preparation process thereof
The invention relates to the field of plastering mortar, in particular to gypsum plastering mortar based on gold tailings and a preparation process thereof.The gypsum plastering mortar is prepared from, by weight, 80-100 parts of cement, 600-650 parts of ardealite, 400-450 parts of gold tailings, 300-350 parts of aggregate, 5-15 parts of admixture and 300-350 parts of water, the mass fraction of iron oxide in the gold tailings is larger than or equal to 8%, and it is tested that the mass fraction of iron oxide in the gold tailings is larger than or equal to 10%. The gypsum plastering mortar prepared by the invention has certain formaldehyde removal capability and excellent mechanical properties, and can reduce the inventory of phosphogypsum and reduce the storage pressure of enterprises.
本发明涉及抹灰砂浆领域，具体为一种基于黄金尾矿的石膏抹灰砂浆及其制备工艺，以重量份数计，包括以下组成成分：水泥80‑100份、磷石膏600‑650份、黄金尾矿400‑450份、集料300‑350份、外加剂5‑15份、水300‑350份，所述黄金尾矿中氧化铁的质量分数≥8%，经过测试，本发明所制备的石膏抹灰砂浆具有一定的除甲醛能力，且力学性能优良，而且可以减少磷石膏的库存，减轻企业的储存压力。
