Approximately 100 million tons of waste foundry sands (WFS) are generated annually worldwide by the foundry industry [2]; 6 million tons are produced by around 3000 Eu-ropean foundries [3]. WFS represents about 80% of the waste produced by the foundry industries, and its disposal involves high costs; in most cases, foundries …

to be decreasing with replacement of foundry sand. Upto 60% replacement of fine sand by foundry sand gives slightly high compressive strength was found tobe optimum. Complete replacement by foundry sand decreasing slight compressive strength, lesser value is 41 MPa which can be used for manufacturing of paver blocks for 40 MPa.
