The aim of this study was to enhance the microstructural activity of micro basalt-fiber
reinforced polymer (GP) mortars incorporating fly ash by adding Nano-Titania. Four distinct dosages of
titania were utilized to make GP mortars with 2% basalt fiber. The microstructural effects of the GP
mixes were evaluated using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). The
SEM analysis revealed that nano-Titania significantly improves the microstructure of GP. The XRD
results showed a rise in hump width between 25° and 35°, indicating the formation of calcium-silicate
hydrate (C-S-H). The incorporation of Nano-Titania into the GP matrix led to a denser microstructure,
contributing to improved mechanical properties. The study concludes that adding Nano-Titania to basalt
fiber-reinforced GP mortars enhances their microstructural characteristics, leading to potential
applications in advanced construction materials.
