Laboratory tests showed the strongest formulation delivered about 30% greater flexural strength than comparable Portland cement bricks while also resisting sulfate attack. To achieve those results, the researchers combined local desert sand with alkali-activated binders. Laboratory tests measured strength and durabilityThe researchers evaluated the bricks through a series of mechanical and durability tests before comparing them with conventional Portland cement products. The researchers describe the approach as part of a circular economy because materials that might otherwise become industrial waste instead become raw construction materials. Those studies will help determine where the material can complement conventional masonry products while making greater use of locally available desert sand.
