Effective Parameters in Gamma Radiation Transmission Rate from Heavy Concrete with Iron Oxide and Barite Aggregates
AbstractThe primary purpose of this study is to investigate the gamma radiation transmission rate from heavy concrete containing iron oxide and barite aggregates. For this purpose, a number of cubic and cylindrical samples of different sizes and types and various percentages of aggregate participation were made. Compressive strength and gamma radiation tests using a cesium-137 source were carried out on specimens. The results showed that the use of heavy aggregates increases the attenuation coefficient of concrete. Increasing the participation of the iron oxide aggregates caused increasing density and thereby intensification of the attenuation coefficient in samples. Such escalation of the attenuation coefficient in concretes containing barite aggregates is higher than the concretes containing iron oxide. The compressive strength of the samples shows a growing trend with the increase in the presence of heavy aggregates, but this increasing trend only endures until the concrete contains 50% heavy aggregates, and thereafter the downward trend occurs for the compressive strength.
