Nanosilica is a silica-based material with particle sizes ranging from 1 to 100 nm, which plays a significant role in enhancing the compressive strength of concrete. This research aims to synthesize high-quality nanosilica using fly ash waste as the primary raw material. The synthesis process was carried out via the precipitation method, utilizing fly ash, sulfuric acid (H₂SO₄), sodium hydroxide (NaOH), and distilled water. Drying temperatures of 80°C, 100°C, and 120°C were applied to evaluate their impact on the synthesized product. The nanosilica produced was characterized using microstructural analysis techniques, including X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). The results of the research demonstrate that lower drying temperatures produce nanosilica with optimal purity, predominantly amorphous structures, and well-dispersed particles. The optimal drying temperature was determined to be 80°C, producing nanosilica with a silica purity of approximately 65%, a crystallite size of 10.89 nm, and phase compositions of 5.24% crystalline and 94.76% amorphous.
