  • Comparison of Physical Properties between Natural Sand and …

    Sand is an important raw material in construction industry. It is the major fine aggregate. There is scarcity of natural sand in large scale because of increased sand mining in river beds leading to lack of natural sand reserves, urban expansion, local legislations and environmental constraints. The industry must find alternatives to meet the growing demand for fine aggregates. So an alternative of this, manufactured sand is produced by the companies to meet the demands. The natural river sand is the product of sedimentation and this river sand contains more impurities than manufactured sand. So river sand sometimes cannot be used for important concreting works. So suitability of manufactured sand is tested. Therefore suitability of manufactured sand is checked by conducting the tests related to physical properties of fine aggregates like ''fineness, bulk density and specific gravity. And tests on fresh concrete using manufactured are also tested. The results of the tests are compared with natural sand. This paper puts forward the suitability of manufactured sand to fulfill the unavailability of natural sand. Therefore manufactured sand can be used as an alternative for natural sand …
