Concrete Sand is coarse in nature and primarily used in the manufacture of ready mix concrete and asphalt. Grading of the sand conforming to IS 383:2016 and Fineness Modulus can range between anywhere from 2.3 to 3.2. It is graded and washed adequately to remove unwanted silt for optimum mix-design. Concrete M-sand is known for its lesser surface water absorption, water & cement saving features and achieving higher compressive strength.
