摘要

Although many eco-friendly additives have been tested in concrete for radiation shielding, the effect of deleb-oxide additive has not yet been studied. This research addresses this gap by utilizing the Phy-X simulation technique to investigate the effects of replacing cement with deleb-oxide additive on the gamma ray shielding performance of concrete (DA0, DA10, DA20, DA30, and DA40). It was noticed that when the cement is being replaced, the density of the produced samples was raising to 2.15 g/cm3 for DA0, 2.22 g/cm3 for DA10, 2.24 g/cm3 for DA20, 2.26 g/cm3 for DA30, and then 2.28 g/cm3 for DA40. The linear attenuation coefficient (µ) at 1.333 MeV was 0.103 cm−1 for DA0, 1.109 cm−1 for DA10, 0.115 cm−1 for DA20, 0.119 cm−1 for DA30, and then 0.123 cm−1 for DA40. In terms of thermal resistivity and structural integrity, the concrete sample DA40 has proven to perform better compared to other examined samples. The high radiation attenuation, thermal stability, mechanical strength, and structural integrity exhibited by the concrete sample DA40 due to the high content of deleb-oxide additive have confirmed it as a better and optimum choice among other tested samples for radiation protection applications.
