CONCRETE FOR RADIATION SHIELDING APPLICATIONS

The density and the water content of concretes used for shielding affect markedly the weight of the reactor shield and thus influence the cost of the nuclear-generated electricity. Among other factors, the bound water depends on the type of cement and filler used, the setting time, and the temperature.
