Abstract This research investigates the potential of utilizing types construction waste as partial cement replacements within concrete formulations. Notably, granodiorite and ceramic powders were introduced at varying substitution ratios. The impact these materials on compressive strength radiation shielding effectiveness traditional was evaluated under both ambient elevated temperature conditions. Additionally, several microstructural tests like X-ray diffraction (XRD), Thermogravimetric analysis (TGA), Energy dispersive (EDX) conducted to assess influence using optimal replacement ratios investigated studied properties concrete. Results revealed a substantial improvement in Remarkably, 7% with powder (WGDP) yielded mix for strength, exhibiting increases 24.7%, 26.1%, 22%, 28% room temperature, 400 °C, 600 800 respectively. Likewise, (WCP) exhibited quantifiable improvements approximately 23.1%, 23.5%, 25.6%, 32.6% For microstructure analysis, XRD confirmed enhanced pozzolanic activity reduced portlandite increased calcium silicate hydrate (CSH) formation WGDP WCP mixes compared control mix. TGA higher CSH decomposition modified mixes, indicating greater reaction. Furthermore, density EDX analyses showed denser microstructures powders-incorporated due finer particle packing secondary hydration effect. investigation show that optimum (C7) enhances attenuation capability WGP (GD7) also contributes positively attenuation, though lesser extent than C7.

Polyurethane-based foam composites: synthesis, structural characteristics, and radiation shielding properties

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 10, 2025

Abstract This study investigates the potential of pure polyurethane (PU) foam as a lightweight, cost-effective shielding material against ionizing radiation, emphasizing its adaptability for incorporating high-performance fillers. PU was doped with various materials, including NiO, ZnO, Cr 2 O 3 , MnO BaO(Fe ) 6 and sludge (at 44.5 wt.% loading), to enhance properties. The synthesized composites were characterized using Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), X-ray Fluorescence (XRF). Radiation performance evaluated through Monte Carlo simulations (MCNP) Phy-X software γ-rays (0.015–15 MeV) fast neutron attenuation (up 11 MeV). Results showed that high-density, high-atomic-number fillers significantly improved γ-ray attenuation, demonstrating highest linear coefficient. Conversely, effectively attenuated neutrons due high concentration light elements. findings highlight PU-based promising materials shielding, particularly in protection radiological safety applications.
