2) As per IS 383:1996 gradation for Crushed sand gives positive result when we compare with river sand. 3) So we can use Crushed Sand as substitute for fine aggregate in concrete. REFERENCES [1] Ahmed, A. E. and EI. Kourd A. A. ( 1989), 'Properties of concrete incorporating natural sand and crushed stone
industry. Natural sand is an essential material utilized for the planning of cement and furthermore plays an important role in the design of mixes. The supply of river sand is inadequate and its continued supply is uncertain, use of Manufactured Sand (M-Sand) and Quarry Dust Sand as a substitute for river sand become inevitable.
M Sand, short for Manufactured sand, is also known as crushed sand or manufactured fine aggregate. It serves as a replacement for river sand in construction projects. Produced by crushing rocks, quarry stones, or larger aggregate pieces into sand-sized particles in a factory or quarry, M Sand possesses a size smaller than 4.75 mm.

to optimise the substitution levels of river sand by crushed sand and help to design the best crushed sand for specific fresh concrete properties. It is well known that the behaviour of mortars at fresh state is influenced by both the rheological behaviour of the cement pastes and the sand particles [16, 17]. Fresh-state mortars and concretes ...
