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.
