The most used construction material in the world is concrete because of its strength, stability and durability. It comprises of four major constituents such as cement, coarse aggregate, fine aggregate and water. From early days onwards river sand is used as a fine aggregate. Due to Scarcity of river sand nowadays M-sand, pit sand etc are used as fine aggregate. Since pit sand is only available at certain regions and due to the scarcity and high cost of river sand and M-sand, it has become necessary to find an alternative for fine aggregate. In this research work weathered crystalline rock sand (WCRS) and dredged sand (DS) are used as alternative for fine aggregate. M40 grade of concrete is selected for this study. Paper discusses mechanical properties of concrete mixes with both WCRS and DS as fine aggregate. Among these mixes, mix with 100% WCRS as fine aggregate showed better results in terms of compressive strength, splitting tensile strength and flexural strength.
