Ultrahigh performance concrete as radiation shielding with mixture of high density mineral

Radiation shielding linear attenuation coefficients μ (cm-1) is highly depends on the density of the material used. Previous studies have shown the mineral known as barite can be effectively used to increase the specific density of concrete structures. Barite in Malaysia is limited; therefore, a...
