Wet-mixed plastering mortar
The invention discloses wet-mixed plastering mortar which is prepared from the following raw materials in percentage by weight: 10-16% of cement, 0-6% of fly ash, 65-75% of machine-made sand, 8-10% of water and 0.3-0.56% of a mortar additive, the additive adopted by the invention can effectively prolong the plastic retaining time of the wet-mixed mortar, also has certain air entraining and retarding properties, and the water reducing rate can meet the use requirements of the mortar, so that the bleeding phenomenon in the early stage of the mortar is avoided, and the construction performance of the mortar is further improved; the wet-mixed plastering mortar provided by the invention has excellent working performance in consistency loss and water retention rate, can be continuously used for 24-48 hours on site, is excellent in water retention rate, can effectively reduce the cracking and hollowing probability after the plastering mortar is formed, does not need to be mixed by adding water for the second time, can be completely mixed according to a design ratio, ensures the construction quality, and has the advantages of low cost and high efficiency. The field labor quantity is reduced.
本发明公开了一种湿拌抹灰砂浆，按照以下重量百分比的原料制成：水泥10％～16％、粉煤灰0～6％、机制砂65％‑75％、水8％～10％、砂浆外加剂0.3％～0.56％；本发明采用的外加剂可以有效延长湿拌砂浆的保塑时间，还具有一定的引气、缓凝性能，减水率也可以满足砂浆的使用要求，避免砂浆前期出现泌水现象，进而改善砂浆的施工性能；本发明提供的湿拌抹灰砂浆，其稠度损失和保水率具有优异的工作性能，能够保证现场24h‑48h连续使用，保水率优良，可以有效减少抹灰砂浆成型后的开裂与空鼓概率，不用二次加水拌制，完全可以按照设计配比拌制砂浆，保证施工质量，减少现场人工数量。
