Performance of High Density Concrete with Iron Ores and Alumino Thermit Portion, As A Radioactive Barrier

High density concrete is widely used in railway, crane counter weight, radiation shielding in nuclear plants or other radiation related application and medical establishment. The aim of this study is to increase the density of concrete and accomplish it by using iron ores, obtain form iron queries as aggregates and thermite portion. The traditional concrete aggregates were replaced by iron ores aggregates in amount of 100% . Physical and mechanical properties (densities C.S., T.S., FreezeThaw resistance were determined). The aggregates of concrete plays an essential role in modifying concrete properties and physical-mechanical properties of concrete. On its shielding properties; the attenuation measurement will perform by using GAMMA SPECTOMETER SCINTILLATION DETECTOR (of Nal) and finds shielding factors (HVL-half value layer, TVL-tenth value layer) as well as attenuation coefficient (μ).
