Also, good quality sand may have to be transported from long distance adds the cost of construction. So that it becomes inevitable to use alternative materials for fine aggregates which include recycled aggregates, manufactured sand, crushed rock powder etc. This paper reports the experimental study of effect of replacement of natural sand by manufactured sand on properties of cement mortar with mix of 1:2, 1:6 and 1:3. Conventional Cement mortar was prepared by using river sand for different cement mortar ratios and replacing the natural sand by M-sand for the levels of 20, 40, 60, 80 and 100%. Mortar cubes of size 70.7x70.7x70.7 mm were casted, cured at room temperature and tested for compressive strength after 3 days, 7 days, and 28 days. Strength and durability characteristics of cement mortar using natural sand, M-sand as fine aggregate at various replacement levels were evaluated and compared. The compressive strength of the cement mortar increases with the increase in M-sand content up to 80%. In prism test it was found that 40 -60 % replacement of manufactured sand shows the higher compressive strength. Water absorption value was found increased with increase in percentage replacement of M-sand. Hence M-sand can be recommended for the replacement of natural river sand in cement mortar up to 80%.
