| Abstract | ||
| One of the most common industrial byproducts created by the construction industry is granite waste. Despite having a special chemical composition, granite waste is nevertheless wasted in large quantities without being recycled, which could have a negative influence on the environment. Because of this, the current study offers a workable strategy for recovering and using granite waste as a flux to create value-added with prominent physical-mechanical properties. The granitic wastes are additives for the purpose of improving natural clay. A batch composition including 20% of granite waste was then created, dried, and fired at various sintering temperatures, including 1100, 1150, and 1200°C. The chemical and mineralogical components of the raw materials were characterized, whereas the mechanical, chemical, and mineralogical characteristics of the fired samples. The results of the fired samples' tests at 1200°C revealed that the samples that had been treated with 20% granite waste had enhanced bulk density from 1.86 to 1.96, apparent porosity from 19.23 to 9.22, modulus of rapture from 24.26 to 37.14, water absorption from 13.82 to 3.74, and chemical resistance from 0.28 to 0.19 to fulfill EN 295: 2013 criteria. The final research approach demonstrated that there is potential to manufacture environmentally friendly pipes with improved physical-mechanical characteristics and a reduction of harmful environmental hazards. | ||
