Development of Geopolymer Foam Mixes towards Building Sustainable Infrastructure

Abstract

            Lightweight Geopolymer Foam (LWGF) material is a novel material. This is an improvement of both the combinations of Foam and Geopolymers developed with 100% utilisation of industrial by-products (Fly ash & GGBS) and by the addition of preformed synthetic foam which increases the further scope of Geopolymers. An alkaline activator (NaOH & Na₂SiO₃) with less concentration is used as binder material.  This provides an eminent solution in developing analternative sustainable building materials. The study includes alkaline to binder ratio and foam to geopolymer pasteparameters to produce LWGF with target density 600-1200 Kg/m³. Fresh and Hardened properties were discussed.
