Chloride Binding Capacity of Fly Ash Cement Pastes.
초록
Chloride ion is considered one of the most common culprits in the corrosion of steel in concrete. It breaks down the passive film and allows the steel to corrode actively at a high rate. The main objective of this study is to determine the critical chloride ion concentrations in the pore solutions and chloride binding effect of cement pastes made with and without fly ash. Cement pastes with water-ratio of 0.5 allowed to hydrate in sealed containers for 28 days and to express poresolution. T도 expressed pore fluids were analyzed for chloride and hydroxyl ion concentrations. It was found that the replaced cement with fly ash have little effect on Chloride binding capacity ratio.
