This study was designed to determine the effects of wood ash on the physical and mechanical properties of fired clay bricks. The clay bricks were fabricated with the addition of 0, 4, 8, 12, and 16% by weight of wood ash. Strength development of brick was cased byfired at 900, 1000, and 1100°C for 40 min. The experimental results demonstrated that the physical property and strength of the fired clay bricks depend on the wood ash contentand firing temperature. Higher wood ash content affected an increase in porosity and water absorption, while the bulk density of the clay brickswas reduced. …
