STUDY ON DURBILITY OF ANTI-WASHOUT CONCRETE

2001-7-29  After 10 years of exposure to marine environment, that of reference concrete is from 5 to 10 times that of anti-washout concrete. Therefore, the anti-washout concrete is durable under marine environment and it is possible to design for durability in the same way as for normal concrete.

2007-1-1  This study aims to evaluate frost durability and steel-bar corrosion in antiwashout-underwater concrete, which has been neglected to date. To achieve this goal, repeated freezing and thawing and accelerated steel-bar corrosion tests have been performed for three types of antiwashout-underwater concrete specimens.

Durability of Prestressed Concrete under Marine

The study on durability of prestressed concrete members in marine environments logs very behind. When we use the prestressed concrete members in the marine environments, there are many subjects. For example they are the problems of corrosion of tendons embedded in the prestressed concrete members and deterioration of concrete in sea water.
