Abstract
The effects of surface protection method on improving the durability of concrete structures are studied. The focuses are placed on the types of surface treatment materials and initial state of concrete (with and without cracks). The specimens used in this research had been exposed to splash zone simulated by shower for 10 years before tests. After exposure, the impregnation depth of water repellent agents, the carbonation depth of concrete and the corrosion condition of steel rebars were measured to examine how the surface protection influenced the corrosion. It was seen that the effect of surface treatment on suppressing the carbonation of concrete was marginal but the corrosion prevention effect depends on the types of water repellent agent. Two types of water repellent agents with large impregnation depths were found to be highly effective in corrosion protection regardless of the existence of cracks in concrete.
