摘要：
The paper presents the results of tests of thermal properties of heavy-weight concrete designed to be used in the manufacturing of small prefabricated masonry elements that can be used in the construction of demountable shielding structures. The specificity of the tested concrete is the use of waste copper slag as fine aggregate instead of sand. The results obtained in the case of two concrete variants (one with basalt magnetite aggregate and the other with barite aggregate) were compared with reference concrete made also in two variants (differing in the type of fine aggregate). The obtained results showed that the use of waste copper slag in shielding concrete significantly reduces the values of its thermal conductivity and specific heat and to a lesser extent also its thermal diffusivity and thermal volume capacity.
