Wet-mixed plastering mortar and preparation method thereof
The invention discloses wet-mixed plastering mortar. The wet-mixed plastering mortar is prepared from the following raw materials in percentage by weight: 35%-45% of stone chips, 25%-40% of yellow sand, 2%-4% of limestone powder, 9%-12% of cement, 2%-4% of mineral powder and 10%-12% of water, with the balance being an additive. A preparation method for the wet-mixed plastering mortar comprises thefollowing steps: (1) weighing the raw materials; (2) mixing the stone chips and the yellow sand to obtain mixed gravel; and (3) sequentially adding the cement, the limestone powder, the mineral powder, the additive and the water into the mixed gravel, and carrying out stirring at a constant speed to obtain the product. Aiming at the current situation that yellow sand and fly ash are in shortage and high in price, the mix proportion of the wet-mixed plastering mortar is actively optimized, the stone chips are used for replacing a part of the yellow sand, and the limestone powder is used for replacing the fly ash, so problems in raw material sources are solved, resources are saved, and enterprise benefits are improved.
本发明公开了一种湿拌抹灰砂浆，由以下重量百分比的原料制成：石屑35％‑45％、黄沙25％‑40％、石灰石粉2％‑4％、水泥9％‑12％、矿粉2％‑4％、水10％‑12％，余量为外加剂；制备方法为：(1)称取各原料；(2)先将石屑和黄沙混合，得到混合沙石；(3)向混合沙石中依次加入水泥、石灰石粉、矿粉、外加剂和水，匀速搅拌，即得。本发明针对目前黄沙、粉煤灰紧张且价格高等现状，积极优化湿拌抹灰砂浆的配合比，利用石屑替代部分黄沙，利用石灰石粉替代粉煤灰使用，既解决了原料问题，节省了资源，又提高了企业效益。
