Abstract
In current scenario, new innovative recyclable materials are scientifically tried to be a part of concrete for improving the properties and reducing the cost. The aim of the present study, is to evaluate the mechanical properties of Fly ash Ground Granular Blast Furnace Slag based Geopolymer Concrete (FGGPC), with partial replacement of fly ash by various percentage of Titanium di oxide (TiO2). In this study, mechanical properties like strength (compressive and split tensile strength) and elasticity properties (modulus of elasticity and modulus of rupture) are assessed, which is basic requirement study for any type of concrete. It is found that, up-to 3% partial replacement of fly ash by TiO2 result in enhanced mechanical properties of FGGPC. Models based on mechanical properties of conventional concrete are available in literatures and standards. Dependency of these models are checked using statistical method and interval concepts. Reliability of the relationships between conventional and FGGPC is validated by Integral Absolute Error (IAE), Mean Absolute Error (MAE), Root Mean Square Error (RMSE), prediction and confidence intervals concepts.
