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 …

A Review on Using Recycled Aggregate with Various Pozzolans in Geopolymer Concrete
Abstract: Reducing the use of natural resources is crucial to solving the global issue of CO2 emissions. Concrete can be produced sustainably by using recycled aggregates and geopolymer binders, which are environmentally benign alternatives to traditional components. Carbon footprints can be reduced by using these materials instead of ordinary Portland cement and natural aggregates. Among all the combinations, recycled coarse aggregates (RCA) and geopolymer concrete have garnered attention as a viable …

Polymeric Actions to Make Recycled Aggregate of Concrete Improved
Abstract: Recycling construction materials of concrete, steel, and steel scraps is an essential technique to promote sustainable material flow. The restricted reuse of recycled concrete aggregate (RCA) can be justified, even in part, by the impact on strength and durability of new RCA-based concrete, instead of natural aggregates. Various research has been conducted on improving RCA effectiveness, in particular resistance and water absorption to disintegration. Application of polymer-dependent therapy was used …
