Neutron shielding concretes (NSCs) are a very important for nuclear reactor design and neutronic investigations. Fast neutron interactions with Ordinary Concrete (OC) and seven different NSC types as Magnetite Concrete (MC), Barite Concrete (BC), Serpentine Concrete (SC), Hematite Concrete (HC), Ilmenite Concrete (IC), Limonite Concrete (LC) and Colemanite Concrete (CC) were simulated by using GEANT4 Monte Carlo toolkit. Simulation results were evaluated in terms of shielding performances, deposited energy by NSCs and produced secondary radiation. •Neutron interactions with Ordinary Concrete (OC) and seven different NSC types were simulated by using GEANT4 Monte Carlo toolkit.•Simulation results were evaluated in terms of shielding performances, deposited energy by NSCs and produced secondary radiation.•Secondary radiation should be taken into account in terms of radiation safety when designing concrete against neutron particles.•It is hoped that the subject and results of this study will raise awareness for researchers for future studies on this subject.
