Abstract
Natural river sand is widely used as fine aggregates in preparation of conventional cement mortar. Due to extraction in excess, natural sand has become a scarce material and it has to be preserved. Manufactured sand (M-sand) has very high potential to replace the natural sand in preparation of cement mortar. This research paper presents a study on replacement of natural sand in cement mortar by M-sand at different percentages. Strength and workability characteristics of 1:6 cement mortar using natural sand and M-sand as fine aggregate at various replacement levels were evaluated and compared. The workability of the cement mortar increases with the increase in M-sand content up to certain level, whereas the strength increases with the increase of manufactured sand. Hence M-sand can be recommended for the replacement of natural river sand in cement mortar.
