dc.description.abstractThis study explores SnO?-based hybrid composite (SnO?-@) doped glass fiber-reinforced concrete (GFRC) for enhanced dielectric, energy storage, and mechanical performance. Microstructural analysis confirmed SnO?-@ promotes ettringite and calcium silicate hydrate (C-S-H) formation, improving matrix integrity. Aged samples exhibited a 650?% increase in surface roughness (Ra) and over 200?% higher Leeb hardness, demonstrating durability. Dielectric spectroscopy revealed frequency-dependent tunability: 1?% SnO?-@ achieved a peak dielectric constant (?' = 130 at 10?kHz), shifting to ?' =?140 at 100?kHz for 2–3?% doping. AC conductivity surged by 60?%, correlating with SnO?-@-induced interfacial polarization and charge mobility. Energy storage capacity improved significantly, attributed to optimized dipole alignment and reduced leakage currents. Color stability remained robust (?E* ? 2.8 post-aging), ensuring aesthetic viability. These results position SnO?-@-doped GFRC as a multifunctional material for smart infrastructure, integrating structural resilience, adaptive dielectric properties, and energy storage potential for next-generation urban applications.
