Proposed mathematical model for stress- strain behaviour of geopolymer concrete

In the present study, appropriate analytic stress-strain mathematical model is developed that can capture real (observable) behaviour of geo polymer concrete. The concrete mixes have shown improved stress values for same strain levels compared to controlled mix in M20 grade. analytical equations response conventional and geopolymer been proposed form y = Ax / (1+Bx+Cx2), both ascending descending portions curves with different set constants. good correlation experimental values. empirical be used as block analyzing flexural behavior sections obtained experiment & G20 grades exhibit a similar trend when modified Saenz model. So successfully evaluated validated
