Structural characteristics of geopolymer concrete beams using alkali-modified blended ash: a comparative evaluation with conventional beams
ABSTRACT This study evaluates the fresh-state rheology and flexural performance of ambient-cured geopolymer concrete (GPC) as a sustainable alternative to M35 grade concrete. Using fly ash and GGBS activated by sodium hydroxide (SH) and sodium silicate (SS), the research investigated a parametric molarity range from 4M...
