artificial sand was found to be 1.856 g/cc. The average void ratio of natural sand and artificial sand was found to be 0.344 and 0.288 respectively. Bulking of artificial sand was higher than natural sand for same percentage of water added. At 8 per cent water content in natural sand and artificial sand, maximum bulking was occurred.
