Tie-confinement aspects of fly ash-GGBS based geopolymer concrete short columns
HighlightsInclusion of GGBS to accelerate the ambient curing of fly ash based geopolymer concrete.Study on the effect of tie-confinement on the stress-strain behaviour of fly ash & GGBS based geopolymer concrete.A single non dimensional stress-strain equation is proposed to predict the stress-strain behaviour of tie-confined GPC.
AbstractThis paper presents the influence of tie-confinement in Fly ash and GGBS based geopolymer concrete (GPC) activated alkaline solution for three different grades i.e., GPC20, GPC40 and GPC60. The grade of concrete, tie configuration and spacing of ties are the parameters varied in this study. Specimens of size 200×100×100mm were cast and cured under outdoor conditions (temperature 35±2°C; humidity 75%) to determine the stress-strain behaviour of confined GPC under uniaxial compression. The obtained results concluded that increase in area of reinforcement the ultimate strength, strain at ultimate strength, post-peak strain response, toughness and ductility were found to be increased. For the better assessment of the stress-strain behaviour of geopolymer concrete a single non dimensional stress-strain model was developed.
