摘要
外加剂对砂浆各性能产生重要影响。主要分析了保水增稠剂、可再分散乳胶粉、减水剂及消泡剂对抹灰砂浆各性能的影响规律，根据影响规律、改性机理及抹灰砂浆国标技术规程，探讨了各化学外加剂在砂浆中最佳掺量的确立方法，并得出了其最佳掺量范围。结果表明：保水增稠剂、可再分散乳胶粉、减水剂、消泡剂最佳掺量范围分别为0．1％～0．15％、1．5％～2％、0．2％～0．25％、0．15％-0．2％时，砂浆性能达到最佳。
Chemical additives have an important influence on the performance of mortar, the effect rules of cellulose ether, dispersible polymer powder, water reducing agent and defoaming agent on finishing mortar were analyzed in this paper. And content determination methods and optimal dosage range of various kinds of chemical additives in cement mortar were discussed according to the effect rules,modifying mechanism of chemical additives and national standard technical specifications. The results show that the mortar can achieve the best performance when the cellulose ether,polymer powder,water reducing agent, defoaming agent dosage range are 0.15%-0.2%, 1.5%-2%,0.2-0.25%, 0.15%~0.2%, respectively.
