Re-usage of waste foundry sand in high-strength concrete The natural fine sand is replaced with waste foundry sand (0%, 5%, 10%, and 15%). The findings from a series of test program has shown reduction in compressive and tensile strengths, and the elasticity modulus which is directly related to waste foundry inclusion in concrete.

Sep 01, 2015· foundry sand are annually used in various foundry sectors. In this study, a series of testing programs was conducted on the fresh and hardened concrete to investigate the re-use of waste foundry sand in high-strength concrete. The control concrete mix-ture was arranged so as to achieve a high-strength concrete of about 65 MPa.
