Physical and Mechanical Properties of Fired Clay Brick Incorporating with Mosaic Sludge Waste

Brick is one of the most common masonry units used as building material. Due to the demand, different types of waste have been investigated to be incorporated into the bricks. Many types of sludge have been incorporated in fired clay brick for example marble sludge, stone sludge, water sludge, sewage sludge, and ceramic sludge. The utilisation of these waste materials in fired clay bricks usually has positive effects on the properties such as lightweight bricks with improved shrinkage, porosity, and strength. Therefore, this study focus on the incorporation of mosaic sludge into fired clay brick. Physical and mechanical properties were conducted such as compressive strength, shrinkage, density and initial rate of suction test. From the results, it shows that brick with 5% of mosaic sludge obtained the best result with highest compressive strength and low initial rate of suction (18.76N/mm2 and 10.08 g/mm2) respectively. Nevertheless, all the other properties for all bricks incorporated with different percentages of mosaic sludge were complied with the standard. In conclusion, mosaic sludge could be an alternative low cost material for brick and at the same time provide a disposal method for mosaic sludge waste.
