摘要
摘 要：研究了可再分散VAE乳胶粉掺量（0、3%、5%）对工程地聚物复合材料（Engineering geopolymer composite，EGC）净浆及砂浆初凝时间、流动度、抗压强度和弯曲韧性的影响。结果表明：随着VAE乳胶粉掺量的增加，EGC净浆及砂浆的初凝时间均延长，流动度和28 d抗压强度均降低；VAE乳胶粉掺量对EGC砂浆弯曲韧性的影响与其体系内的纤维类型及掺量密切相关，在适宜的纤维体系配合比条件下，适量的VAE乳胶粉能在一定程度上提升EGC砂浆的弯曲韧性。
Abstract：The effects of redispersible VAE latex powder content (0, 3%, 5%) on the initial setting time, fluidity, compressive strength, and bending toughness of engineering geopolymer composite(EGC) paste and mortar were investigated. The results show that with the increase of VAE latex powder content, the initial setting time of both EGC paste and mortar prolongs, and the fluidity and 28 d compressive strength both decrease. The effect of VAE latex powder content on the bending toughness of EGC mortar is closely related to the fiber type and content within its system. Under appropriate mix proportion of fiber systems, the incorporation of appropriate content of VAE latex powder can enhance the bending toughness of EGC mortar to a certain extent.
结论
（1）针对含不同纤维增强相的EGC净浆及砂浆体系，VAE乳胶粉的掺入延长了各组EGC净浆及砂浆的初凝时间，降低了流动度和28 d抗压强度，且随着掺量的增加，各性能指标降幅增大。
（2）VAE乳胶粉掺量对EGC砂浆弯曲韧性的影响与其体系内的纤维类型及掺量相关，在适宜的纤维体系配合比条件下，适量的VAE乳胶粉能在一定程度上提升EGC砂浆的弯曲韧性。相较而言，PVA与PP复掺体系对VAE乳胶粉的适应性更好。
