Masses for obtaining poured concrete, concrete for bricks, concrete for tiles or mortar are known, in which Portland cement and Colemanite, water and additives to regulate the process are involved as aggregate. The invention achieves a remarkable increase in the capacity of neutron radiation protection of the material. For this, Portland cement is replaced by Alumina cement and a new component is inserted into the mass, specifically anhydrous calcium sulfate, the Colemanite staying as aggregate.
