The chloride migration diffusion coefficients of bagasse ashblended
concrete specimens are represented in Table 5. The diffusion
coefficient of bagasse ash-blended concrete specimens continuously
decreases with increases in the ash content up to 25%. At
30%, there is an increase; however, the value is less than that of
control. This observation is true for both 28- and 90-day cured
specimens. These data indicate that chloride diffusion is considerably
reduced by partial replacement of high-strength portland
cement with bagasse ash. These results also indicate more
than a 50% reduction in diffusion coefficient value for 20%
