This document presents the results of an experimental study on the partial replacement of demolition waste in fly ash bricks. Fly ash, demolition waste, stone dust, and cement were used as raw materials to manufacture bricks. Stone dust was used to replace demolition waste at levels of 22%, 25%, 30%, and 35% by weight. The bricks were tested for compressive strength and water absorption after 7, 14, and 28 days of curing. The compressive strength of the bricks increased with curing time and reached a maximum of 8.55 N/mm2 for bricks with 30% stone dust replacement. Water absorption also decreased with curing time and was lowest for bricks with 35% stone dust replacement. The study shows that demolition waste
