Workability and Compressive Strength of Mortar with Manufactured Sand

Sand obtained from river stream is broadly utilized as fine aggregate in manufacturing of ordinary mortar. Because of extraction in abundance characteristic sand has turned into a scare material and it must be protected. Sand obtained from crushing of stone have better particles shape, size and surface textures than natural river sand due to controlled degradation of natural rocks and have very high potential to replace the natural sand in preparation of cement mortar. Present paper investigate the effect of manufactured sand in mortar in terms of workability and compressive strength. To accomplished this manufactured sand was replaced with river sand in mortar for different percentage level at an interval of 10 and investigate the workability and compressive strength for the mix. Results show that manufactured sand can be replaced with river sand for gaining the strength and use a dose of super plasticizer to maintain proper workability at a particular proportion of water cement ratio.
