Physical, structural, and mechanical properties of the concrete by FLUKA code and phy-X/PSD software

Abstract

The present study aims to investigate radiation shielding, physical, structural, and mechanical qualities of the marble concrete via the FLUKA code, newly developed Phy-X/PSD software, and analytical method. In the present work, these characteristics are explored for four types of marble concretes namely, MC0%, MC10%, MC20%, and MC25%. Findings show that the thinnest MC25% is needed to reduce the initial intensity to half of it, and as a result, less volume of selected shielding material is required. In addition, the Energy Absorption Buildup Factor (EABF) and Exposure Buildup Factor (EBF) reach the highest values at 40 mfp for MC10%. Moreover, the Transmission Factor (TF) related to the marble concrete samples illustrates that by increasing the energy, the samples’ efficiency will reduce. Furthermore, using Makishima–Mackenzie Model (MMM), structural and mechanical properties of selected shielding materials are evaluated. The outcomes depict that the elastic moduli decrease from MC0% to MC25%. Also, the largest values of mechanical moduli require the highest values of bond dissociation energy (Gt) for various marble concrete samples.
