The present review manuscript examines the most essential phases in the developments of the inorganic class of environmentally benevolent Geopolymer concrete focusing on the valorisation of Waste of Glasses in context of incorporation in the manufacturing of Geopolymer concrete, especially concerning to its properties and applications. Their long-standing applications as structural materials developed through activation of alkali, i.e., Geopolymerization, in the field of sustainable constructions and infrastructures industries, diverse GPC are on the map. Even though, more advanced studies in the context of the said concept will be proved valuable to concerned industries people and of course, to the researchers themselves. Although the available literature in this innovation zone is few and far between, it breaks the surface, for the most of the centre of attention on its, incorporation with other waste materials pointing a finger to its approach to embrace ‘‘waste for the best” strategy. Previously, their character is neither wellfigured out nor aptly welcomed as in the ordinary Portland Cement based edifice materials enjoying. That is the core reason and objective of this article that review of its handy restricted literature to throw lights on the valorisation of blending of Waste of Glasses for the manufacturing of Geopolymer concrete centring its attributes and uses establishing it as a soon-to-be useful lucrative and sustainable global building material. The suggestions pointed out here in this manuscript will confidently be accommodating for potential research works on the topic. However, a modest challenge viz., curing complications, sometimes practical confronts of application, constrained supply chain, and a prerequisite for an observant directive of mix design for its fabricating, are standing up in its tracks to substitute Ordinary Portland Cement counterparts. Even so, when produced by utilizing vast and within reach precursors, activators and waste glass materials under up to the standard quality control of diverse characteristics, predominantly strength and green footprints of alkali activators, valorisation of Geopolymer concrete incorporated with waste glasses are momentous forthcoming part of the prospect toolbox of sustainable and economically reasonable construction materials. Eventually, the paper categorizes promotion of applications and most importantly the properties aspect for this promising novel type of building material.

Introduction

Concrete technology has witnessed a revolution since Romans era. Nowadays, a trend towards less energy-intensive, green, innovative, affordable, sustainable user-friendly building materials with low carbon footprint is the subject of attraction to researchers [1–4]. The application of diverse recycled solid waste is drawing the attention of engineers to incorporate them with construction composites. The market for recycled materials like concrete aggregates has been initiated through a project to develop it by Flemish Public Environmental Agency (OVAM) in 2006. It’s conclusion suggested that top-level recycled aggregates often finish up in substandard applications owing to the lack of certainty about the technical performances of recycled aggregates viz., consistency of properties, porosity, the presence of Chlorides, Sulphates, etc. and deficiency of regulations to encourage their applications with elevated added value [5].
