Numerical Study on Flexural Behavior of Alkali-Activated Slag Concrete Beam by ANSYS

Geopolymer concrete is a type of concrete that is made by reacting aluminate and silicate-bearing materials with a caustic activator, such as fly ash or slag from iron and metal production. It can be a suitable substitute for ordinary Portland cement (OPC). Geopolymer concrete is considered green concrete because of the reduced CO₂ emission and due to the usage of waste materials for manufacturing. Several investigations are happening on the topic of geopolymer concrete in structural members like beams, columns and slabs. This work focuses on the numerical analysis of the flexural behaviour of alkali-activated reinforced slag concrete beam under cyclic loading. Numerical study was conducted using finite element tool, ANSYS. For this, a numerical model was developed and modeled. Thereafter, cyclic load was applied on the same beam to obtain the load-deformation curve. From this curve, the first crack load, ultimate load, maximum deformation, ductility index and energy absorption capacity were obtained.
