Environment-friendly dry-mixed mortar admixture and preparation method thereof
The invention relates to an environment-friendly dry-mixed mortar admixture and a preparation method thereof, and the environment-friendly dry-mixed mortar admixture comprises the following components in percentage by mass: 85%-95% of cement kiln ash, 2%-6% of cellulose ether, 0.5%-1.5% of an air entraining agent, 2%-7% of a water reducing agent and 0.5%-2% of a thickening time control agent. The cement kiln ash is used as a carrier, so that wastes are recycled, the cement consumption is reduced, the environment is protected, materials are saved, thickening, water retention, air entraining, water reduction, dispersion and setting time adjustment are integrated, and the problems that in a high-temperature environment in summer, a mortar mixture is rapid in water evaporation, large in layering degree, large in consistency loss and prone to surface cracking are solved. The prepared dry-mixed mortar is good in water retention performance, excellent in construction performance and low in shrinkage rate.
本发明涉及一种环保型干混砂浆外加剂及其制备方法，环保型干混砂浆外加剂包括以下组分，按质量百分比计为：水泥窑灰：85％‑95％、纤维素醚：2％‑6％、引气剂：0.5％‑1.5％、减水剂：2％‑7％、调凝剂：0.5‑2％。本发明使用水泥窑灰作为载体，使得废物再利用，并节约水泥用量，环保节材，并集增稠保水、引气、减水分散及调节凝结时间于一体，解决夏季高温环境下，砂浆拌合物水分蒸发快、分层度较大、稠度损失大、表面易开裂的问题，制成的干混砂浆保水性能良好、施工性能优良、收缩率低。
