(S081)Estimation of alka alkallii dissolution from steelmaking slag in water

摘要

To suppress the alkali elution elution,, when using steelmaking slag near sea and river river, , we have studied the dissolution behavior of each min mineral phase in steelmaking slag eral with and without slag modification [1] 1]. . Then, the mineralogical phases phases, , that cause the alkali elusion elusion, , were clarified [[2, 2,4] 4].. Based on this result, several slags were synthesized and the suppression of the alkali elusion b byy the control of the mineralogical phase phases s was shown [3,4] 3,4]. . To design the slag composition by the slag modification, in this study, a model to estimate of each mineral phase.
