Valorisation of glass wastes for the development of geopolymer composites - Durability, thermal and microstructural properties: A review

The present review paper examines the essential stages in the developments of the innovative category of eco-friendly inorganic Geopolymer concrete throwing lights on the Waste of Glasses valorisation concerning their amalgamation in producing Geopolymer concrete particularly pertaining to its durability properties. The process of Geopolymerizati on is capable enough to produce diverse GPC in the field of sustainable infrastructures and constructions industries. Nevertheless, more advanced investigations with respect to its durability viz., Drying shrinkage behaviours, Sulphate Attack, Leaching Test, Ultrasonic Pulse Velocity and thermal properties as well as heavy metals immobilization along with micro-structural attributes like porosity, XRD and SEM analyses will altogether prove to be worthy to people related to construction industries, researchers, engineers, etc. Though, the literature in this novel sector is little and isolated and found mostly on their blending with other profuse wastes. Until now, their character is not fully outlined and not broadly accepted in contrast to Ordinary Portland Cement based building composites. For this reason, a review of its literature to focus on the valorisation of incorporating of Waste of Glasses in production of Geopolymer concrete emphasizing on its durability characteristics to promote it as durable and sustainable large-scale construction material along with cost-effectiveness too. When GPC is produced employing accessible precursors, activators blending with glass wastes under the standard quality control of principally durability properties and low carbon footprints of alkali activators, valorisation of these types of GPCs are vital approaching part of the future toolbox of durable and sustainable as well as cost-effective building materials. Ultimately, the manuscript categorizes its endorsement as durable structural materials for widespread applications as a promising new-fangled kind of edifice material. (C) 2019 Elsevier Ltd.
