Utilization of Agro-Industrial Waste in Production of Sustainable Building Blocks

Increase in industrial waste has led to an environmental concern. Such types of waste are directly dumped on land, which can cause pollution. This waste should be used in the construction of building materials such as building blocks, which not only helps in reducing pollution but is also a cost-effective choice to design sustainable buildings. Brick is usually one of the essential construction materials, generally prepared from clay, shale, soft slate, calcium silicate, stones, etc. In view of utilizing agro-industrial waste, this study focused on the consumption of cupola slag and rice husk ash to develop sustainable building blocks. Cupola slag and rice husk ash were used in various proportions and cement is used as a binder with a constant ratio. The physicomechanical properties of developed sustainable building blocks were carried out and it meets the requirements of Indian standards. The results shows that the cupola slag–cement–rice husk ash mixture can be probably used in the manufacturing of economical bricks.
