Effect of Physical Properties of Manufactured Sand as Fine Aggregate in Elastic and Shrinkage Properties of Concrete and Mortar

Abstract:

Common river sand is expensive due to excessive cost of transportation from natural sources. The increased sand mining affects the aquifer of the river bed and causes many environmental problems. Also large-scale depletion of these sources creates environmental problems. In such a situation the manufactured sand can be an economical alternative to river sand. Manufactured sand is defined as the residue, tailing or other non-valuable material after the extraction and the processing of rocks to form fine particles less than 4.75mm. Use of manufactured sand as a fine aggregate in concrete and mortar draws serious attention of researchers and investigators. Aggregate makes up a significant portion of concrete. The physical properties of aggregate play an important role in elastic and shrinkage properties of concrete and mortar. In this paper, the effect of manufactured sand as fine aggregate in tensile, elastic and shrinkage properties of concrete and mortar are discussed.
