Impact on Thermal Properties of Burnt Clay Bricks using Foundry Sand

— Industrial waste such as foundry sand and many others are posing problems to manufacturing industries as strict environmental policies are not allowing open dumping or stacking of these waste materials. To solve the problem many countries are using these wastes as construction material in various areas of construction. In this work, use of foundry sand and sawdust with various percentages is done to manufacture clay bricks. Percent replacement of soil is done by 20%, 30% & 40% with foundry sand and compared with normal bricks from three different manufactures from different areas. At 20% replacement of foundry sand bricks have shown optimum thermal and physical properties.
