In this study, blended cement-stabilized barite fillers against gamma rays and neutrons have been developed with the use of the maximum density method by considering various amounts of water (100-300 kg/m3), binder (4-10%), and compaction energy (500-2000 kJ/m3). According to the experimental series of these filler materials, satisfactory response surface results have been achieved in the study. The experimental results revealed that compacted filling material can ensure an efficient shielding capability for gamma rays and neutrons when designed with a density of 3.064 g/ cm3. An increase in binder content, water content, and compaction energy has improved the compressive strength of these materials up to 37 times according to that of the poorest series. Neutron and gamma-ray shielding capabilities were found to be 119 and 14% higher than those of the poorest filler material, respec-tively when theoretical and experimental results are considered in the study.eninfo:eu-repo/semantics/closedAccessAnti-radiation fillerMaximum density methodStabilization with blended cementPhysical and mechanical propertiesGamma-ray and neutron shielding capabilityArticle16110.1016/j.pnucene.2023.1047432-s2.0-85159555666Q2WOS:001009285700001Q1
