“…The possible application of glass foams largely relies on the ratio of open and closed porosity [135]. The existence of micro, round, and closed cells in porous materials is an efficient way to create high thermal insulation and high coupling strength, according to the concept of heat transmission [136][137][138]. Rincón et al produced glass ceramic foams by applying "weak alkali activation" to aqueous suspensions made of soda-lime glass and coal fly ash.…”

Alkali-activated materials are gaining much interest due to their outstanding performance, including their great resistance to chemical corrosion, good thermal characteristics, and ability to valorise industrial waste materials. Reusing waste glasses in creating alkali-activated materials appears to be a viable option for more effective solid waste utilisation and lower-cost products. However, very little research has been conducted on the suitability of waste glass as a prime precursor for alkali activation. This study examines the reuse of seven different types of waste glasses in the creation of geopolymeric and cementitious concretes as sustainable building materials, focusing in particular on how using waste glasses as the raw material in alkali-activated materials affects the durability, microstructures, hydration products, and fresh and hardened properties in comparison with using traditional raw materials. The impacts of several vital parameters, including the employment of a chemical activator, gel formation, post-fabrication curing procedures, and the distribution of source materials, are carefully considered. This review will offer insight into an in-depth understanding of the manufacturing and performance in promising applications of alkali-activated waste glass in light of future uses. The current study aims to provide a contemporary review of the chemical and structural properties of glasses and the state of research on the utilisation of waste glasses in the creation of alkali-activated materials.

“…The effect of a foaming agent on making FA-based geopolymer blocks using glass powder have achieved the lightweight, energy-efficient building material by increasing the foaming agent to reduce density and thermal properties by satisfying the strength parameters as per the code provisions by Singh et al [78]. The results predicted that energy consumption is significantly saved by 8.94% and 10.47% during the operational stage by conducting energy simulation analysis using the eQuest simulation tool.…”

Use of bricks and their manufacturing process plays an important role in the construction sector. Despite its various methods of manufacturing, still large quantities of bricks are used in the building construction. Manufacturing of bricks consumes large quantities of natural resources, and it is energy intensive. Similarly, due to rapid industrialization large quantities of waste industrial byproducts are generated and causes handling and disposal challenges of these wastes. This review work attempts the possibilities and potential use of various types of waste industrial byproducts in fired and unfired bricks. This study also highlights the importance of waste and its usage guidelines in bricks manufacturing to enhance the strength and durability properties. To overcome the challenges associated with bricks manufacturing, firing is still considered as the most preferred method of making bricks. Use of industrial waste byproducts to the mix matrix of fire and unfired bricks will overcome the disposal challenges and reduce the depletion of natural resources. Since sustainability is a key factor that is considered when it comes to making bricks, innovative methods are needed to produce them using sustainable materials. The production and application of bricks and their usage guidelines are reviewed further in various aspects such as environment, social, economic, and technology to meet global standards and policies of the local government for sustainable development.

“…[40], along with workability in the fresh state [58,60,61], altogether have established them as promising construction materials as a substitute of OPC-composites. Furthermore, on account of adequate mechanical attributes in hardened conditions [55,58,59,62], and brilliant performances in the context of durability [41,42,56,58], geopolymer composites have proved themselves as a possible emerging green replacement of ordinary Portland cement [63][64][65][66][67][68][69][70][71][72][73][74]. The process of geopolymerization includes the use of alkaline solutions to activate minerals of geological origin like metakaolin or industrial by-products such as fly ash that is desirably rich in alumina and silica, producing a three-dimensional (3D) polymeric structures which sustain load-mechanics.…”

It is a universal fact that concrete is one of the most employed construction materials and hence its exigency is booming at a rocket pace, which in turn, has resulted in a titanic demand of ordinary Portland cement. Regrettably, the production of this essential binder of concrete is not merely found to consume restricted natural resources but also found to be associated with emission of carbon dioxide—a primary greenhouse gas (GHG) which is directly answerable to earth heating, resulting in the gigantic dilemma of global warming. Nowadays, in order to address all these impasses, researchers are attracted to innovative Geopolymer concrete technology. However, crack development of various sizes within the concrete is inevitable irrespective of its kind, mix design, etc., owing to external and internal factors viz., over-loading, exposure to severe environments, shrinkage, or error in design, etc., which need to be sealed otherwise these openings permits CO2, water, fluids, chemicals, harmful gases, etc., to pass through reducing service life and ultimately causing the failure of concrete structures in the long term. That is why instant repairs of these cracks are essential, but manual mends are time-consuming and costly too. Hence, self-healing of cracks is desirable to ease their maintenances and repairs. Self-healing geopolymer concrete (SHGPC) is a revolutionary product extending the solution to all these predicaments. The present manuscript investigates the self-healing ability of geopolymer paste, geopolymer mortar, and geopolymer concrete—a slag-based fiber-reinforced and a variety of other composites that endow with multifunction have also been compared, keeping the constant ratio of water to the binder. Additionally, the feasibility of bacteria in a metakaolin-based geopolymer concrete for self-healing the cracks employing Bacteria-Sporosarcina pasteurii, producing Microbial Carbonate Precipitations (MCP), was taken into account with leakage and the healing process in a precipitation medium. Several self-healing mechanisms, assistances, applications, and challenges of every strategy are accentuated, compared with their impacts as a practicable solution of autogenously-healing mechanisms while active concretes are subjected to deterioration, corrosion, cracking, and degradation have also been reviewed systematically.
