Study Of Sand Having More Organic Impurities<br>
<br>

<strong>Abstract</strong><br>
The organic impurities in sand primarily comprise of carbon material in the form of decay of vegetables, trees and
remains of animals. This paper covers an approximate determination of presence of possible injurious organic compounds in
natural sand, which is to be used in cement mortar or concrete. The value of the test determines whether further test of the
sand regarding its reactiveness with cement mortar/concrete is necessary before it is approved for use. This method is of
significance in making a preliminary determination of acceptability of sand. When a sample subjected to this test produces
darker colour, then it is advisable to perform the test for the effect of organic impurities on compressive strength of
mortar/concrete prepared using this sand.
