Feasibility of quarry dust to replace river sand as fine aggregate of concrete r w c n rajapaksha and h p sooriyaarachchi abstract high cost and scarcity of river sand is one of the main problem faced by construction industry today. use of substitutions like offshore sand in particular to replace river sand is
Jun 02, 2016· One possible source of construction aggregate is sand that has been manufactured from the surplus material (crusher dust) that results when coarse aggregate is produced in hard rock quarries. Coarse aggregate production typically yields 25% to 45% crusher dust depending on the parent rock, crushing equipment and crushing conditions [ 2 ].
Recent research into the potential of quarry dust in cement mixes have focused upon a partial replacement of the sand. The results to far suggest that a cement mix made of quarry dust has an increased workability, making it more flexible and easy to use, but there are doubts about its durability, and compressive strength.
