ABSTRACT Concrete‐like materials like glasscrete, woodcrete, hempcrete, and ashcrete present alternatives to traditional concrete used for building materials. This study focused on characterizing concrete‐like glass ceramics to determine its strength for applications where compressive stress and other harsh factors are prevalent. Glass ceramics was developed by combining borosilicate waste glass obtained from laboratory ware with silicon carbide. Which was processed, analyzed, and mixed in three different percentage variation: 60:40, 70:30, and 90:10. The mixed batches were compacted into shapes of tiles and fired at 900°C and the glass ceramics were analyzed by X‐ray diffraction and scanning electron microscopy and property test like compression strength and water absorption were carried out. The resultant glass ceramics indicated a major presence of mullite crystalline phase and a glassy phase, also the property tests showed that the glass ceramics produced exhibit better properties than materials like traditional concrete used for building applications like pavements. The integration of silicon carbide powder into the structure of the glass powder during its liquid phase, enhanced the formation of closed pores and the formation of a polycrystalline phase which includes mullite. This contributes to improving the strength of the concrete‐like glass ceramic.
