Modeling of physico-chemical characteristics of concrete for filling trenches in radioactive waste management

An optimization of concrete used for immobilization of radionuclides 60 Co and 137 Cs, is presented. A relatively simple mathematical model is given, which permits minimization of leach rate and permeability and maximization of compressive strength. An optimal solution, based on experimental data, is given. These results will be used for a future Serbian radioactivewaste disposal center
