STUDY ON DURABILITY OF SURFACE COATINGS PERFORMED ON A EXISTING CONCRETE STRUCTURE

Abstract

The durability of surface coatings is evaluated through the accelerated tests and the examination of a existing concrete structure. In the accelerated tests, weatherability, elasticity, and permeability of chloride, oxygen and vapor were tested.
The selected surface coatings through the accelerated test are painted on the existing concrete structure and have been exposed to the marine environment for 8 years. The surface coatings were sampled from the structure and external appearance, crack-bridging ability and bond strength of coatings were examined.
