Several mortar mixtures were prepared with different proportions of BFMW ranging from 0% to 30% as fine aggregate replacement. Cement mortar mixtures were evaluated for density, compressive and tensile strengths, and gamma ray radiation shielding. The results revealed that the mortar mixes containing 25% BFMW reaches the highest compressive strength values, which exceeded 50 MPa. Evaluation of gamma-ray attenuation was both measured by experimental tests and computationally calculated using MicroShield software package, and results have shown that using BFMW aggregates increases attenuation coefficient by about 20%. These findings have demonstrated that the mine waste can be suitably used as partial replacement aggregate to improve radiation shielding as well as to reduce the mortar and concrete costs.}, journal={Annals of Nuclear Energy}, publisher={Elsevier BV}, author={Gallala, Wissem and Hayouni, Yousra and Gaied, Mohamed Essghaier and Fusco, Michael and Alsaied, Jasmin and Bailey, Kathryn and Bourham, Mohamed}, year={2017}, month={Mar}, pages={600–606} }
