Effects of Rice Husk Ash and Brick Waste on the Properties of Construction Bricks

Abstract:

This research reports the effects of rice husk ash and brick waste on the properties of construction brick. Clay is the raw material for producing brick. Both rice husk ash and brick waste are waste materials which can be added to clay to produce better quality brick with lower cost. Bricks of size 77mm x 38mm x 26mm were produced by stiff mud process. Three different sized rice husk ash and brick waste were used in different amounts (5%, 10%, 15%, and 20% by volume) as a partial replacement of clay while preparing the bricks. Some properties like drying and firing shrinkage, bulk density, and cold crushing strength were measured. There was decrease in drying and firing shrinkage, slight reduction in bulk density and decrease in cold crushing strength with increasing the rice husk ash and brick waste particle percentages.
