摘要: 为确保亚热带气候区桥面铺装施工中薄层环氧砂浆与混凝土梁体之间的黏结质量,对不同环氧砂浆在不同施工工艺条件下进行了对比试验研究。研究表明:环氧砂浆底胶由于强光暴晒老化,影响其黏结强度,随着暴晒时间的延长,黏结强度明显降低;对暴晒过的底胶表层打磨清洗后,可以消除阳光暴晒的影响;采用免底胶环氧砂浆施工可保证黏结强度。

Abstract: Comparison tests and studies of different epoxy mortar were conducted under different working conditions, in order to ensure the bonding performance between the thin epoxy mortar grout layer and concrete bridge beams in the bridge deck pavement engineering at sub-tropical areas. The results show that the bonding strength of the primer of epoxy mortar will be affected when it is exposed to the strong sunshine; with the increase of exposure time, the bonding strength decreases significantly. However, the influence of exposure under the sunshine can be erased by grinding and cleaning the exposed primer surface. Moreover, the application of epoxy mortar without primer can ensure the bonding strength.
