Paper Title
Study Of Sand Having More Organic Impurities

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.
