摘要
通过对聚合物改性砂浆与混凝土劈裂强度的研究,探究了几种不同粗糙度和界面剂对砂浆与1 d,28 d龄期混凝土粘结强度的影响。试验发现良好的界面粗糙度、界面剂的使用能够提高聚合物改性砂浆与混凝土的粘结强度;砂浆与1 d混凝土的粘结效果好于28 d混凝土。
Through the research of splitting strength of polymer modified mortar and concrete,influence of different surface roughness and interfacial agents on splitting strength of mortar and 1 d and 28 d age concrete were explored. It indicated that suitable roughness and interfacial agents can enhance splitting strength between mortar and concrete. The bonding effect between mortar and 1 d concrete age is better than that of 28 d concrete.
