Aug 01, 2010In this study, the potential re-use of waste foundry sand in high-strength concrete production was investigated. 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

CONCRETE MIXING RATIOS

Concrete mixing ratios for cement, sand, aggregate, and water are generally mixed as 1 part cement, 3 parts sand, and 3 parts aggregate or stone with just enough water to make it workable. The ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture.
