Abstract: The face quality,strength of surface,abrasion-resistant properties and permeability properties of ship lock concrete,adopting vacuum dewatering method combined with controlled permeability formwork technology,are studied in indoor experiments and field application.The research results indicate that make use of the technology instead of changing concrete mix can efficiently lower the water-cement ratio of surface concrete,and improve the face quality and compactness of surface concrete;at the same time,the anti-abrasion and impermeability performance of concrete can be improved by means of this technology.
