Keywords:sorption distribution coefficient , cement-based material

In the construction of pits for near surface disposal, various cement-based materials are used in addition to the representative cement-based material(solid phase) assumed in the safety assessment. We will introduce the sorption distribution coefficient data on the various cement compositions, as data collection of the latest knowledge at the time of construction.
