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

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.

Automated summary

The present study investigates the radiation shielding, physical, structural, and mechanical qualities of different types of marble concrete using FLUKA code, Phy-X/PSD software, and analytical method. The results show that MC25%, the thinnest type, is needed to reduce the initial intensity to half, requiring less volume of shielding material. MC10% exhibits the highest Energy Absorption Buildup Factor (EABF) and Exposure Buildup Factor (EBF) at 40 mfp. Moreover, the Transmission Factor (TF) of the marble concrete samples reveals a decrease in efficiency as energy increases. The Makishima-Mackenzie Model (MMM) is used to evaluate the structural and mechanical properties of the selected shielding materials, showing a decrease in elastic moduli from MC0% to MC25%, with the highest values of mechanical moduli requiring the highest values of bond dissociation energy (Gt).
