仿清水混凝土保护材料在船闸主体混凝土涂装中的应用

Application of imitation fair-faced concrete protective materials in concrete coating for ship lock body

船闸混凝土外观质量的提升是船闸工程建设的重要课题,也是船闸工程美化的关键因素。为了解决船闸混凝土外观质量存在的问题,采用实验室试验和现场应用相结合的方法,评价仿清水混凝土保护材料的物理性能、耐候性能、耐污染性能和装饰效果,总结其涂装施工过程中的质量控制措施,并以岷江龙溪口船闸主体工程为例,验证该材料在船闸工程中的可行性和优越性。结果表明,清水混凝土保护材料能够渗透、防水、封固、抗老化,有效提高船闸混凝土的耐久性和美观性,并具有较高的经济效益和环境效益。

Improving the appearance quality of ship lock concrete is an important topic in the construction of ship lock engineering and is also a key factor in the beautification of ship lock engineering.To solve the appearance quality problems of ship lock concrete,we adopt the combination of laboratory tests and field application to evaluate the physical properties,weather resistance,pollution resistance,and decorative effect of imitation fair-faced concrete protective materials.We summarize the quality control measures during the coating construction and verify the feasibility and superiority of the material in the ship lock engineering by taking the main project of the Longxikou ship lock in Minjiang River as an example.The results show that the proposed material has penetration,waterproofing,sealing,and aging resistance abilities,thereby improving the durability and aesthetics of ship lock concrete,which has high economic and environmental benefits.
