| 内容記述 | The purpose of this study was to develop salt leaching control technology by solidifying fly ash with cement. Cylindrical specimens with different porosity were prepared to determine the parameters of the leaching model. Three cubic specimens with different size were prepared to clarify the relation between the specific surface area of the specimen and the leaching amount per specimen weight. Tank leaching tests were performed on these cylindrical and cubic specimens. As the porosity of specimen increased, the rate constants of surface dissolution were decreased, and the ratio of volume of specimen contributing to surface dissolution were increased. As the specific surface area was decreased, dimensionless cumulative leached amounts of Na, K and Cl were decreased, which means that leaching of salts from cement solidified fly ash could be controlled. In the non-depleted region, the actual leaching from cubic specimen was expressed by the proposed leaching model very well in both cases where the ratio of the maximum leaching amount per surface area was considered constant and where the depth contributing to surface dissolution was considered constant. | |||||
