This work investigates the recycling of sugarcane bagasse ash waste as a method to provide raw material
for clay brick bodies, through replacement of natural clay by up 20 wt.%. Initially, the waste sample was
characterized by its chemical composition, X-ray diffraction, differential thermal analysis, particle size,
morphology and pollution potential. Clay bricks pieces were prepared, and then tested, so as to determine
their technological properties (e.g., linear shrinkage, water absorption, apparent density, and tensile
strength). The sintered microstructurewas evaluated by scanning electron microscopy (SEM). Itwas found
that the sugarcane bagasse ash waste is mainly composed by crystalline silica particles. The test results
indicate that the sugarcane bagasse ash waste could be used as a filler in clay bricks, thus enhancing the
possibility of its reuse in a safe and sustainable way.
