摘要

Waste materials are a significant worldwide problem that affects health, so the innovative approach of recycling waste glass into construction materials is essential for its potential to reduce environmental pollution and promote sustainability in the construction industry. The present investigation focused on benefiting recycled glass as a partial-weight substitute Nano-powder for the soil to produce local green brick in order to reduce non-biodegradable waste and make it useful material. The raw materials included local soils from Iraqi quarries and recycled glass bottles characterized in terms of chemical composition and mineralogy. Various amounts of Nano-glass with different mixtures were conducted with a percentage of recycled glass (0%, 10%, 20%, and 30%) under elevated temperatures (800, 900, and 1000 °C) for 1 h. The technological properties (density, absorption, compressive strength, porosity, and efflorescence) were studied. Moreover, X-ray diffraction at various temperatures was used to examine the microstructure of the treated samples. Through the experimental results, it was disclosed that nanoparticles help to upgrade “physico-mechanical” properties and rules as geopolymer binders in the brick matrix, which can provide an environmentally friendly and effective option for brick improvement. Moreover, it had been to produce “eco-friendly bricks” with optimal mechanical qualities by using 20 wt% of recycled Nano-glass at 1000 °C. As the compressive endurance increased by 84%, density and shrinkage increased by 8% and 133% sequentially. The absorption and porosity decreased by 21.4% and 40%, respectively. Moreover, the x-ray showed that the crystalline quartz in clay and the “glass phase” merged with the brick matrix, speeding up the densification process and having certain positive benefits on the properties of eco-friendly bricks.
