Investigation of Radiation Shielding Properties of Polypropylene Fiber Reinforced Shotcrete

Abstract

Fibre concrete has emerged in order to improve the properties of concrete and to create an economical building material. In this study, the radiation permeability of shotcrete reinforced with polypropylene fiber was investigated. For this purpose, linear attenuation coefficient was measured for shotcrete reinforced with polypropylene fiber, produced using the dry mixing process. The linear attenuation coefficients for dry mixed shotcrete have been measured at photon energies of 1173, 1332 and 662 keV. Measurements were carried out using gamma spectrometer containing NaI (Tl) detector and a Multichannel Analyzer (MCA). The linear attenuation coefficients have increased with the increasing fiber percentage for all studied gamma energies.

Effects of the γ‐irradiation strength and basalt additive content on the mechanical performance and dielectric response of polypropylene films

“…Resistant additives to the polymer, such as basalt and metal oxides, can eliminate this effect. A great deal of scientific research has also been done to ensure that PP and its composites are suitable radiation‐shielding materials . In this respect, a low‐cost and high‐performance engineering polymer, PP, was chosen as a host matrix for improving its mechanical and dielectric properties via an electromagnetic irradiation process.…”
