摘要：The demand of natural sand in the construction industry has increased a lot resulting in the reduction of sources and an increase in price.Thus an increased need to identify a suitable substitute, that is eco-friendly and inexpensive quarry dust being extensively used as an alternative to the sand in the production of concrete.In this paper an attempt has been made to determine the properties of hollow concrete blocks produced by replacing sand by quarry dust.Both partial (i.e.50% ) and complete replacement has been tried with and without admixtures.Four different proportions have been considered.In two proportions studies have been made by considering different W/C ratios.
