Description

<p>This study was conducted on concrete using blast furnace cement Class B and metakaolin-based artificial pozzolan (MKP) as mineral admixture. Two curing methods, water curing at 20℃ and air curing after demolding, were used to evaluate permeability of substances at 1 month, 6 months and 1 year. When the water curing was continued for MKP mixed concrete, sift of pore size distribution into smaller size, smaller chloride ion diffusion coefficient, and smaller water permeation rate coefficient were observed. A correlation was also clarified between the chloride ion diffusion coefficient and surface electrical resistivity in this study.</p>
