STABILIZATION OF LEAD IN LOW-LEVEL RADIOACTIVE WASTE FORMUSING LOW-ALKALINITY CEMENTS

摘要

Leaching behavior of lead from waste forms solidified using low-alkalinity cements wasrnstudied to reduce the leachability of lead from low level radioactive waste forms. The lowalkalinityrncements used to solidify lead were calcium sulpho-aluminate cement blended silicarnfume and cement glass. Two kinds of leaching tests and an unconfined compressive strengthrntest were conducted. This study shows that calcium sulpho-aluminate cement blended silicarnfume effectively decreases the leachability of lead from the cement-solidified waste forms.
