Design and simulation of concrete reinforced with Fiber as a shield to Gamma and Neutron radiations

In this paper, the goal is to design and simulate some concrete samples reinforced with Fiber as well as containing  Bohr in order to be utilized as a shield to nuclear radiations (Gamma & Neutron).by presenting experimental composing projects for heavy and ordinary concrete containing  Bohr ,heavy and ordinary concrete reinforced with Fiber , proper ratios  for stuff  were computed. Then using nuclear computations with computational code of MCNPX for Neutron and Gamma`s radiant spectra, the required Bohr, polypropylene Fiber, and steel percentages were obtained in order to be used in plain, Fiber, and heavy concrete material. In the next stage, ten concrete samples were analyzed in final experiments. Finally, reinforced concrete material weakening coefficients using   MCNPX code were computed and the level of Neutron and Gamma radiating for every composing project was separately attained.
