摘要：

This study, adhering to the Chinese standard GB/T 34008-2017, introduces a penalty-function-based particle swarm optimization algorithm and proposes an innovative approach for optimizing the aggregate mix ratio in radiation-shielding concrete. Utilizing barite, magnetite, and hematite as aggregates, the proposed optimization method yielded optimal mix ratios tailored for shielding 4.5 and 10 MeV neutrons while achieving target compressive strengths of 35 and 40 MPa. Geant4 simulations and experimental validations confirm that the optimized concrete offers robust neutron and gamma-ray shielding...
