General shielding requirements are discussed with particular emphasis on fast neutron shields. Concrete materials which are effective in meeting the requirements are outlined and the basic principles involved are explained . The concrete mix, type and source of materials, and strength properties of the shields of four similar nuclear reactors are compared. Effects on concrete setting time and strength of adding boron in the form of mineral colema-nite and borocalcite and the counter effects of calcium chloride are described.
