Bricks are commonly utilized construction materials composed of sand, cement, and water in standardized ratios. Such demand of construction materials could result in the exhaustion of natural resources. In order to tackle this problem, researchers are investigating the utilization of alternate substances including tea waste and silico manganese slag as partial replacement for sand and cement respectively in bricks. The study utilized a sand/cement ratio of 1:2.5 and a water/cement ratio of 0.5, along with the inclusion of 5-15% tea waste and 10-20% silico manganese slag in the mix percentage. The experimental findings demonstrated that by substituting tea waste and silico manganese slag into the cement brick, the brick exhibited sufficient compressive strength and water absorption properties, satisfying the minimum masonry unit requirements specified in the British Standard of 1985. Furthermore, the density of the cement brick with tea waste and silico manganese slag was found to be lower than the solid bricks, classifying it as a lightweight brick. All of the cement bricks containing tea waste and silico manganese slag met the criterion for the effective strength to weight ratio, except for the bricks made with 15% tea waste and 10% silico manganese slag. Based on the results, it was determined that the proposed mix proportion for the cement brick was the brick consists of 15% tea waste and 20% silico manganese slag. Such brick with the highest effective strength to weight ratio of 1.16 was suitable to be used in the construction industry.
