Abstract | Geopolymer Concrete has been extensively studied in the past and recognised as a greener substitute for Ordinary Portland Cement (OPC) concrete. Geopolymer concrete is proven to have good engineering properties with a reduced carbon footprint. Geopolymers not only reduce the greenhouse gas emission but also use a large amount of industrial wastes such as fly ash and slag. This environmentally friendly material is being embraced by the construction industry after its use in the Global Change Institute at University of Queensland. However, research into the use of geopolymer concrete in structural applications is very limited. This research paper aims at investigating the applicability of a constitutive relationship that authors developed for OPC concrete in predicting the constitutive relationship of geopolymer concrete. This model has the capacity to predict the lateral dilation of concrete which in turn will be used to establish the confinement provided by the lateral reinforcement in column applications. Load deformation behaviour of twelve geopolymer concrete slender columns reported in the literature is used to validate the proposed model. Since geopolymer concrete exhibits higher brittleness than OPC concrete, careful consideration should be given in the structural design of geopolymer concrete. Predicted behavior for slender geopolymer concrete columns using the proposed stress-strain relationship for confined geopolymer concrete is in good agreement with the experimental results. The outcomes of this paper will be useful in the structural analysis of geopolymer concrete columns. |
