Investigating the linear attenuation coefficient and compression strength parameters of heavy concrete with barite aggregates containing bismuth powder and microsilica powder against gamma rays

In the production of heavy concrete, instead of typical aggregates, heavy aggregates or steel spalls, cast iron or lead is used; The use of such concrete is to prevent the emission of radiation such as X and gamma; Basically, this kind of concrete is used in structures related to nuclear facilities,...
