Numerical Analysis of Double Geopolymer Concrete Layer with Different Properties

Abstract

Researchers have been working to find alternatives to conventionally produced concrete in recent years. Geopolymer concretes are also the focus of these studies. There are not enough studies on modelling geopolymer concretes, which are the subject of many experimental studies. In this study, which is believed to close the gap in the literature, stress and strain analyses of geopolymer concrete with two different properties under load in two different systems were performed. The locations of the concrete with different properties were also changed in the model, and the results obtained in both cases were compared. It was observed that when the geopolymer concrete with a lower modulus of elasticity and 100% slag content was on top, the stress values decreased, and the strain rates increased.
