The present study investigates the bond strength and flexural behavior Of Geopolymer-based Reinforced Concrete (GPRC) beams to assess their suitability as sustainable alternatives to conventional concrete structures. Geopolymer Concrete (GPC) prepared with industrial byproducts, Fly Ash (FA), Ground Granulated Blast Fu...
To promote the valorization of red mud (RM), a high-volume industrial solid waste, engineered geopolymer composites (EGC) were developed using a ternary binder comprising ground granulated blast-furnace slag (GGBS), fly ash (FA), and RM. Ten mixtures were designed using a simplex-centroid method, and the effects of bin...
ABSTRACT Alkali-activated materials (AAM), which are derived from aluminosilicate substances and activators, represent a sustainable and low-carbon alternative to ordinary Portland cement (OPC). The incorporation of fibers helps mitigate brittleness and enhance toughness. An orthogonal experimental approach was used to...
This study investigates the combined effects of waste glass powder (WGP) and waste tire fiber aggregate (TFA) on the mechanical and microstructural performance of fly ash (FA)–ground granulated blast furnace slag (GGBS)-based geopolymer concrete (GPC). Previous studies generally examined WGP and TFA separately, therefo...
Expansive soils, featuring severe swelling-shrinkage behavior and low bearing capacity, pose persistent challenges to geotechnical infrastructure. As a promising alternative to lime and cement stabilizers, calcium carbide residue-rice husk ash (CCR-RHA) blends have been widely investigated, but existing studies focus m...
The development of low-carbon binders from industrial solid wastes can reduce Portland cement use and support sustainable construction. However, the combined roles of alkalinity supply, sulfate reaction, and reactive silica supplementation in ground granulated blast furnace slag (GGBS)–calcium carbide slag (CCS)–desulf...
