Abstract

The diffusion of uranium (U(VI)) in solid cement monoliths of ordinary portland cement (OPC) and low-heat portland cement containing 30 wt. % fly ash (FAC) was measured by an in-diffusion technique. Detailed sharp depth profiles of uranium in the solid cement matrices were successively and quantitatively measured using laser ablation microprobe inductively coupled plasma mass spectrometry (LAMP-ICP-MS), and the apparent (Da) and effective (De) diffusion coefficient of uranium in cement matrix were calculated as: Da =∼ 4 × 10-16 m2 s-1 and De =∼ 3 × 10-11 m2 s-1 for OPC, and Da =∼ 2 × 10-17 m2 s-1 and De =∼ 6 × 10-13 m2 s-1 for FAC.
