Abstract |
We experimentally investigated the mechanical and radiation shielding properties of hybrid concrete incorporating amorphous steel fibers and ultra-fine boron powders. Various mix proportions were developed to maximize radiation shielding performance while maintaining adequate workability and mechanical strength. Slump tests, compressive strength tests, and gamma-ray shielding tests were conducted to examine the relationship between mechanical and shielding properties. The results indicate that the addition of amorphous steel fibers enhances crack resistance and structural performance, while the addition of boron powders significantly improves radiation shielding performance. These findings suggest that such hybrid material can serve as a balanced radiation shielding solution with both mechanical durability and radiation attenuation capabilities.
