Improvement of Durability and Appearance of Concrete Structures by Finishing Materials

Abstract

The reinforced concrete structure is always influenced by CO₂ in the air. Furthermore, a certain structure is subject to the effect of chloride and freezing and thawing action. Consequently, deteriorating phenomena appear in some structures, such as crack in the concrete, corrosion of reinforced bar, and excessive deflection in the member, and these cause a decrease in the durability and damage in the beauties of the structure. This article describes how successfully deterioration can be controlled and beauty appearance promoted by the protection of the reinforced concrete structure with the application on the surface of various kinds of finishing and impregnating materials.
