Abstract: Background:To enhance the shielding properties of concrete mixtures, there is a tendency toward using various additives while most of these additives being used either pose hygiene hazards or require special handling processes.Purpose:To ensure the concretes being environmentally friendly and providing sufficient gamma ray radiation shielding efficiency, Bi2O3-loaded concrete mixtures are researched and optimized. Methods:Both experimental and theoretical methods were used to calculate the linear attenuation coefficient before using the Taguchi method to optimize concrete's mix proportion which includes cement quantity, water-to-cementitious material ratio, Bi2O3 rate and sand ratio. Results:The shielding abilities and mechanical properties of Bi2O3-loaded concretes were improved compared with ordinary concrete. There was small inconsistency between results obtained by MCNP5 (Monte Carlo N-Particle 5) program and experiment. Conclusion:It was suggested in the study that the most important parameter affecting the attenuation of the concrete's radiation is the Bi2O3 rate while cement quantity is the following factors, and the effects of water-to-cementitious material ratio and sand ratio are negligible.
