Sustainable High-Strength Geopolymer Composite Reinforced with Nano-Silica and Basalt Fibers: Mechanical and Microstructural Evaluation
Abstract: Sustainable soil composites (SSC) were formulated by incorporating red earth with varying proportions of bagasse ash (BA) and hydrated lime to enhance geotechnical performance and promote the reuse of agro-industrial waste. Red earth served as the primary structural matrix, BA functioned as a pozzolanic filler, and lime acted as a chemical stabilizer. BA content ranged from 0% to 60%, identifying 10% as the optimum level for significant improvement, and lime …
