Use of wood sawdust ash as effective raw material for clay bricks

Abstract

The world is gradually looking for waste material properties and finding a way out of using it as secondary raw materials for other industrial purposes because of increasing environmental understanding and guidelines on controlling industrial waste. In the present world, the researcher’s primary aim is to enhance the usage of environmentally friendly materials and protect the environment. This research proves the possibility of using wood sawdust ash (WSDA) partially replace clay and sand manufacturing bricks. This paper used WSDA obtained from controlled combustion to replace other construction materials for bricks. The feasibility study used WSDA as an admixture with five distinct replacement levels, 5%, 10%, 15%, 20%, and 25%, for non-modular bricks (230×110×70) mm. The brick was evaluated for various strength parameters to authenticate clay bricks’ compressive strength, efflorescence, and water absorption properties. The findings revealed that the compressive strength of WSDA bricks (11.01 N/mm2) is higher than fly ash-cement-based and burnt clay bricks, which are 6.93 N/mm2 and 9.56 N/mm2. Also, the water absorption is (31%) lower than clay burnt bricks.
