as Manufactured sand. Concrete made with crushed stone dust as replacement of natural sand in concrete can attain the same compressive strength, comparable tensile strength, modulus of rupture and lower degree of shrinkage as the control concrete 2. From Literature Review it is observed that
To achieve a good concrete the manufactured sand should have somewhere between 510 mass percent of fines depending on rock type. It is common that manufactured sand has around 1525 mass percent of fines after the crushing stage. In this thesis, dry air classification has been investigated to reduce the amount of fines in manufactured sand.
