Abstract

A method of treating cement, so that when compounded, e.g. into blocks, protection is afforded against nuclear radiation, comprises adding, during or after grinding a material to counteract moisture during storage and a proportion of barytes. Preferably 0,01% to 2% by weight, of moisture-resistant material and 60% to 95% of barytes are incorporated and up to 3% by weight of gypsum may also be included. A plaster contains 7 parts by weight of barytes and 1 part by weight of a mixture of cement, moisture-resistant additive and gypsum.
