Abstract: In the present study, the effects of replacing sand by different percentages of basic-oxygen furnace slag on compressive strength, bulk density and gamma ray-radiation properties of mortar have been investigated. Replacement percentages were 0, 40, 80 and 100% by weight of used aggregate. Likewise, linear and mass attenuation coefficients, half-value and tenth-value layers in addition to mean free path for the tested samples were measured. The results indicated that the strength properties of mixtures increased significantly upon replacing sand partially by iron slag. It is also revealed that the inclusion of iron slag as a partial replacement to sand enhances the bulk density of mortar. On the other hand, the replaced fine slag sample at level 100% has significant effects on shielding efficiency in thick shields, as it reduces the capture gamma-rays better than the conventional mortar.
