Paver Bricks from Foundry Waste Sand

The foundry industry expands to meet increasing demand for cast components. Green sand has become a critical and important environmental priority. This work demonstrates a feasible, reusable solution by utilizing foundry waste sand into the production of eco-friendly paver bricks, using a composite mixture of 60% waste sand, 25% cement, 10% gravel, and 2% coconut fibre. By assessing the fitness of these materials for practical use, this study provides an alternative to traditional burnt clay bricks, effectively reducing the heavy dependence on landfills for sand disposal and mitigating the environmental degradation associated with conventional brick manufacturing.
