시멘트 고화체 침출율 예측

Prediction of Cement Waste-Form Leach Rate

김창락, 최광섭, 조찬희, 김진웅

초록

물질전달이론에 근거한 시멘트 고화체의 세가지 침출모형을 제시하여 비교해 보았다. 시멘트 고화체의 침출에 있어서 확산식 사용의 가능성과 확산식을 사용할 때 표면농도가 포화농도에 빠르게 접근한다는 가정의 타당성을 보였다.

Three leaching models of cement waste-form based on mass-transfer analysis are compared. The applicability of diffusion equation to predict cement waste-form leaching and the reliability of the assumption used in the diffusion-controlled leaching model that the waste-form surface concentration is rapidly approdching the saturation concentration of the dissolved species are confirmed.
