| 内容記述 | In this study, a tank leaching test was conducted under the conditions where the difference between tank leaching solvent concentration and leaching concentration became large in order to clarify the effect of external concentration on the leaching concentration of easily soluble salts from cement solidified fly ash. Distilled water, solvent-1 and solvent-2 were used as solvent in the tank leaching test. Under distilled water conditions, reducing L/S ratio increased the difference in leaching concentrations. The concentrations of solvent-1 and solvent-2 didn’t have a very significant suppression effect on the leaching concentrations. Enlarging the specimen of cement solidified fly ash could suppress the amount of leaching per weight per area of the specimen. In particular, it was found that the leaching suppression effect was significant during the elapsed time of 0.125 day, where surface leaching can control the leaching phenomena. Although it is not considered that a specimen size affects the amount of leaching per weight per area, in this study, the specimen size affected the amount of leaching per weight per area after the elapsed time of 0.25 day, where diffusion can control the leaching phenomena. |
