As the demand for sustainable construction practices increases, alternative materials are being explored to reduce waste and carbon emissions. This study investigates the feasibility of utilizing recycled geopolymer binder as a substitute for ordinary sand in the production of geopolymer mortar. The study examines the effects of various replacement rates of recycled geopolymer on the physical, mechanical, and thermal properties of the geopolymer mortar. The results indicate that geopolymer mortar incorporating recycled geopolymer binder as a replacement for ordinary sand exhibits similar mechanical properties to traditional geopolymer mortar, with minor decreases in compressive and flexural strength as the replacement rate increased. The geopolymer mortar also demonstrated lower thermal conductivity than traditional mixes, resulting in increased thermal insulation. These findings suggest that using recycled geopolymer binder as a replacement for ordinary sand in geopolymer mortar production could be a promising approach for sustainable construction practices.

“…However, the most significant decrease was observed at 800 • C, which was caused by the loss of water from the structure of materials. Moreover, Chindaprasirt et al [48] confirmed the profitable effect of the incorporation of fine auto glass on the fire-resistance performance of fly ash-based geopolymers.…”

Nowadays, humanity has to face the problem of constantly increasing amounts of waste, which cause not only environmental pollution but also poses a critical danger to human health. Moreover, the growth of landfill sites involves high costs of establishment, development, and maintenance. Glass is one of the materials whose recycling ratio is still insufficient. Therefore, in the presented work, the influence of the particle size and share of waste glass on the consistency, morphology, specific surface area, water absorption, setting time, and mechanical properties of geopolymers was determined. Furthermore, for the first time, the fire resistance and final setting time of such geopolymer composites were presented in a wide range. Based on the obtained results, it was found that the geopolymer containing 20% unsorted waste glass obtained a final setting time that was 44% less than the sample not containing waste glass, 51.5 MPa of compressive strength (135.2% higher than the reference sample), and 13.5 MPa of residual compressive strength after the fire resistance test (164.7% more than the reference sample). Furthermore, it was found that the final setting time and the total pore volume closely depended on the additive’s share and particle size. In addition, the use of waste glass characterized by larger particle sizes led to higher strength and lower mass loss after exposure to high temperatures compared to the composite containing smaller ones. The results presented in this work allow not only for reducing the costs and negative impact on the environment associated with landfilling but also for developing a simple, low-cost method of producing a modern geopolymer composite with beneficial properties for the construction industry.

“…There is slight variation on the various properties of auto glass waste based geopolymer mortar. The report was found a low thermal conductivity coe cient of 0.56-0.70 W/m K by adding 80-100% AGW in the mix combination [2]. Recycled aggregate based geopolymer concrete has no signi cant severe crack probagation and the formation of e orescence [3].…”

The usage of industrial by-product Flyash (FA) and Boiler Sand (BS) in connection with alkali activators in the manufacturing of geopolymer concrete was investigated. Cement is the most important binding component in Concrete and it plays vital role in the Construction Industry. In the current decades, Cement manufacturing units are producing more than 300 million metric ton cement which creates global warming problems because of the release in carbon dioxide (CO2). In the society it is great thread to the environment and human health. This scenario has been changed by preparing new development of cementitious materials instead of cement in the Concrete. Alkali activator based geopolymer act as good binding material in the concrete. The binding capacity of the geopolymer addressed by using Class F FA, Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) with proper mix ratios. One of the main issues faced by Tyre Industry, in Tirunelveli is the disposal of used boiler sand. Boiler sand used as insulating agent for the boilers in the industries it is obtained around 55 tonnes per week. The idea was proposed the usage of BS in the preparation of geopolymer concrete which leads to reduce the storage problems. The utilaization of BS create economic aspect in the development of concrete. The various trial mix design was made with replacement of Sand by BS of 10%, 20%, and 30% respectively. With this above mentioned various mix proportions Pave blocks are to be manufactured and the various properties are verified with IS 15658:2006 guidelines.
