BEHAVIOUR OF MAGNESIUM POTASSIUM PHOSPHATE CEMENT UNDER LEACHING
The effectiveness of the use of magnesium potassium phosphate cements (MKPC) as protective matrices for radioactive waste was investigated in this work from the point of view of the main elements leaching. Fly ash and blast-furnace slag were used as MKPC fillers. Leaching tests were performed on monolithic MKPC samples according to ANSI/ANS 16.1 test. Based on the obtained data, the cumulative leaching fractions, leaching mechanisms, effective diffusion coefficients and leaching indices K, Mg, P, B, Si, Al, and Ca were determined. The values of the calculated leaching indices (>10) of the constituent elements indicate that the characteristics of the studied MKPC matrix are acceptable for radioactive waste immobilization.
