混凝土施工缝弥合剂防水砂浆及其应用研究

Waterproof Mortar with Concrete Construction Joint Agent and Its Practice

提出了一种治理隧道混凝土施工缝渗漏水的外加剂新技术——弥合剂砂浆防水技术。工程试验表明，采用弥合剂砂浆代替橡胶止水带，可操作性强，防水可靠，具有显著的经济效益。在隧道混凝土衬砌工程中有良好的推广应用前景。

In this paper,a new technology about the waterproof agent for concrete construction joint in tunnel has been studied.The experience in construction shows that the technology of wateproof mortar with joint agent in stead of rubber joint belt characterized by well workable,well water repellence and notably technical and economical benefits.Waterproof joint agent is useful and has great value in construction practice of tunnel lining.
