摘要：The present work focuses on the optimization of the conditions of resin waste stabilization in cement matrices. The cemen ted resins matrices have been performed by mixing, in appropriate proportions, the radioactive resins, the Portland cemen t and sand with the water. Seven formulations have been carried out by incorporation the spent resin in amounts ranging from 8.3% to 15%. Stud y showed that we can increase the amount of the resin in the cement matrix fro m 8.3% to 12%. Under these conditions, the mechanical strength of the package increases by 73% and the porosity by 8%. Leaching tests on the resulting package reveal that the formulation that incorporates 12-13% of the spent resin does not reject cesium. On either side, very lo w Cs departure of 11.4% is noticed for all formulations.
