Abstract

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.

磷酸镁钾水泥在浸出作用下的行为

从主元素浸出的角度研究了磷酸镁钾胶结剂(MKPC)作为放射性废物防护基质的有效性。采用粉煤灰和高炉矿渣作为MKPC填料。根据ANSI/ANS 16.1测试，对单片MKPC样品进行浸出试验。在此基础上，确定了K、Mg、P、B、Si、Al和Ca的累积浸出分数、浸出机制、有效扩散系数和浸出指标。计算出的各组成元素的浸出指数(>10)值表明，所研究的MKPC基质的特性可用于放射性废物的固定化。
