摘要
可再分散性乳胶粉(SWF)是聚合物改性砂浆中的主要组分。探讨了SWF的作用机理,研究了SWF掺量对砂浆粘接强度、压缩强度、弯折强度和抗冻融能力等影响。实验结果表明,当w(SWF)≥20%时(占干聚合物改性砂浆的质量分数),其综合性能得到显著改善。
The redispersible emulsion powder（SWF） are a main components in polymer-modified mortar The action mechanism of SWF was discussed, the effects of SWF content were studied on the bonding strength, compressive strength, flexural strength and anti-freeze-thaw of mortar. The experiment results showed that the combination property were obviously improved when mass fraction of SWF was not less than 20% in dry polymer-modified mortar.
