Abstract

Diffusion coefficients of iodine (I), cesium (Cs) and strontium (Sr) in solid cement blocks of ordinary portland cement (OPC) and low-heat portland cement containing 30 wt% fly ash (FAC) are measured by in-diffusion experiment. By using “laser ablation inductively coupled plasma mass spectrometry”, the penetration profiles of trace elements by diffusion were obtained quantitatively in cement solids. The apparent diffusion coefficients of the near-surface of the cement samples were estimated to be about 10-13 m2 s-1for I, Cs and Sr. Lower diffusion coefficients were observed for FAC than those obtained for OPC.
