Study on the Investigation Methods on Deterioration of Surface Finishing Paintings for Reinforced Concrete Urban Collective Housings

Part 4 Protection Effects of Finishing Coating materials for RC based on 10years outdoor exposure

Abstract

Finishing material which is used at construction of reinforced concrete acts the part of resisting the carbonation and protecting the durability of construction.However, examination by using data of long-term outdoor exposure is not only lacked, but not also taken into account for factor affected by condition of local environment. In this research, velocity coefficient in terms of carbonation was compared as difference according to local region and averaged annual temperature, and the effect inhibiting carbonation of finishing material was analyzed. As the results, results of long-term carbonation inhibition according to the carbonation. resistant R induced by experiments of carbonation promotion can be expected and carbonation resistance and chloride penetration resistance may be made clear.
