Abstract

Ultra-high strength concrete produced with agro-residual wastes and industrial by-products were tested for radiation shielding capacity by measuring the linear attenuation coefficient, half value layer and tenth value layer. The linear attenuation test results, show that the ultra-high strength concrete with agro-residual and industrial wastes can be effectively employed in shielding the radiation. The half value layer results reveal that radiation shielding concretes can be produced using industrial and agro-residual wastes, by concentrating equally on the enhancement of both the homogeneity and density of the concrete matrix. The ultra-high strength concrete developed in this investigation registered a better radiation shielding properties than that of the conventional anti-radiation shielding concretes with high dense aggregates which are costlier and found to have environmental degradation along with the health hazards.

Key words: ultra-high strength concrete, radiation, linear attenuation coefficient, half value layer, tenth value layer
