This investigation systematically explores the attributes of self-compacting Geopolymer
concrete (SCGC) in both its fresh and hardened states, with a particular emphasis
on the introduction of Nano-alumina (Al2O3). The study encompasses nine distinct
SCGC formulations, each integrating differing proportions of Nano-alumina (NA) –
ranging from 0% to 1.5%. SCGC was prepared using (100) % ground granulated blast
furnace slag (GGBFS), (50) % Slag, (50) % Fly-ash(FA), "and 100% Fly-ash
(FA)"with a constant alkaline activator to binder ratio of 0.5. A combination of sodium
silicate solution (Na2SiO3) and sodium hydroxide solution (NaOH) with a predetermined
ratio of (2.5) was selected as the alkaline activator for this study. A comprehensive
set of tests, encompassing fresh state and hardened concrete evaluations such as
slump, flow-ability, workability, flexural strength, impact strength, and compressive
strength, were conducted to assess the mechanical properties of self-compacting Geopolymer
concrete (SCGC). The acquired experimental outcomes underwent detailed
analysis to elucidate the performance characteristics of SCGC. Furthermore, correlations
between experimental figures were evaluated to explore the interlink between
fresh and hardened phase properties of Geopolymer concretes. The experimental results
show that the use of Nano-alumina had significant effects on the fresh state characteristics
of concrete. Additionally, adding (1.5) % Nano-alumina to the mixture significantly
improved the mechanical functioning of the SCGC samples.
