新型耐久性防护材料在水闸建设中的应用研究

Study on Application of New Durable Protection Materials in Water Gate Construction

文章着重介绍了优止水、施而固、永凝液3种新型水泥基渗透结晶型耐久性防护材料,对新材料的抗渗性和抗碳化性进行了室内试验和对比分析,对其在武障河闸和北六塘河闸分别进行了现场应用和测定。实践证明:该新型材料对提高混凝土耐久性有良好的效果,具有广泛的应用空间。

In this paper, three new cement-based permeable crystalline durable protection materials of Youzhishui, Shiergu and Yongningye are addressed. Lab test, comparison and analysis are carried out concerning their impermeability and carbonization resistance of the new materials. Their site tests and application are implemented simultaneously on Wuzhanghe gate and Beiliutanghe gate. Practice shows that this new material is with good effect on improvement of concrete durability and with wide application potential.
