Numerical Evaluation of Alkali Activated Reinforced Geopolymer Concrete Column

Geopolymer concrete is a type of concrete that is made by reacting aluminate and silicate-bearing materials such as fly ash or slag from iron and metal production with a caustic activator. It can be a suitable substitute for ordinary Portland cement (OPC) concrete. Geopolymer concrete is considered as green concrete since the reduced CO2 emission and due to the usage of waste materials for manufacturing. A lot of studies are undertaken in the field of the usage of geopolymer concrete in structural members such as beams, columns, slabs, etc. In this paper, geopolymer concrete columns are modeled using the Finite Element Modeling software ANSYS, and the behavior of the same column under axial loading and eccentric loading is studied. The axial behavior of the geopolymer concrete column is compared with the axial behavior of the conventional M30 concrete column and also the behavior of the geopolymer concrete column under axial load is compared with that of 50mm eccentric load.
