Numerical Analysis of Alkali Activated Geopolymer Concrete Slab under Impact Load
Researchers focuses on their study on sustainable and environmentally friendly building materials like Geopolymer concrete (GPC). There were several studies done in the literature to find the performance of GPC structural members under different loading conditions and checked their performance against Ordinary Portland cement (OPC) concrete. Slabs are the most important structural members and it is very significant to find the behaviour under impact loads and it is not always adequately understood. The purpose of this study is to examine how an alkali-activated slag slab behaves under impact loading and utilizing the ANSYS software, a 3D nonlinear finite element analysis was performed. To validate the numerical model that was utilised, the slab models were first calibrated using existing experimental data and then parametric tests were conducted utilising various reinforcement ratios and their spacings. The results showed that GPC slabs showed better performance and the deformation decreased with increase in reinforcement ratios.
