ENHANCED SHIELDING AND MECHANICAL PROPERTIES OF WHI TE CEMENT MORTARS VIA CELESTOBARITE FINE AGGREGATE

This study emphasizes using barite mine wastes as a ggregate material in blended mortar as an improved gamma-ray shielding structure in nuclear applications. Mortar mixtures made of white cement were prepared with v arious percentages of waste ranging from 0-30% as partial ep acement of sand. Evaluation of density, flexura l and compressive strength, and gamma-ray shielding were conducted. T he increase in the percent of the barite wastes agg regates affects the gamma-ray attenuation coefficients. The results tes tifi d that the mine waste is appropriate as partia l substitute to enhance gamma-ray shielding, ensures sustainability of natu ral resources and reduces the mortar and concrete c osts.
