The recovery of silica nanoparticles from agricultural waste, such as wheat, rice, and millet husk ash, provides an environmentally friendly approach for the management of waste and the development of new materials. XRD and FTIR results of silicanoparticles in millet husk ash revealed the existence and crystalline nature of silica as well as their purity, structural quality and significant applicability of the materials. Surface engineering, functional insights have been obtained from FTIR spectra through surface modifications and composition while demonstrating such molecular vibrations that are responsible for the functionality in future technologies. As a construction material, Rice Husk Ash-Silica Nanoparticles (RHASNP) exhibits a prospect as an alternative binder to cement, either maintaining or improving the compressive and tensile strengths up to 10% replacement level, even as workabilty reduces. The results highlight the potential of agro waste derived silica for food grain conservation, nanocomposites, catalysis, biomedical application and environmental benign concrete. Further investigation aimed at optimization of the synthesis procedures, enhancement of the performance and widening of the industrial applications are recommended.
