ABSTRACT The deficiency of sand in the river made a novel interest in the researchers. The contributions regarding sand of river diminishment and requirement for exploitation made scientific management of resources available. Here, the sand from foundry could be utilized in the form of partial substitution of fine components or overall substitutes of fine components and the addition of supplementary to attain divergent concrete properties. The concrete has been substituted with optimal aggregate & micro silica has been substituted partially with foundry sand that is of waste. The STS & CS tests has been performed during 28 & 7 days. The highest strength has been attained at substitution of 15% of sand taken from foundry. When compared with plain cement concrete, blended concrete containing micro silica has exhibited greater improvements.
