The maximum tensile strength of concrete is obtain at 60% and 70% replacement of natural sand with Crushed sand. The concrete with crushed sand performed better than concrete with natural sand as the property of crush sand is better than that of natural sand.
Sand made by other types of machines is flaky, which is troublesome in working. The Jaw crushers, are generally used for crushing stones in to metal/aggregates. Manufactured sand from jaw crusher, cone crusher, roll crusher often contain higher percentage of dust and have flaky particle. IS Code Provisions
40% replacement of sand by crusher dust. Hence it could be concluded and recommended that crusher dust could be effectively used in concrete of above grades for replacement levels of sand by 30-60% economically leading to sustainable development. Index Terms- Crusher dust, sand, workability, strength.
Natural sand is depleting at a very fast pace and efforts are being made to conserve it. The major solution to this problem is to use manufactured sand produced by crushers such as those provided by PROMAN. Manufacturing concrete sand is proving to be the best solution that balances the demands for environment protection and higher economic growth.
Generally, the concrete crushing station is composed of a concrete crusher (sand making machine), a screening machine, a feeder, a conveyor belt, a steel frame, a drive system, an electric control system, a motor unit and the like. Working principle of mobile concrete crusher
Stone Sand is a waste material found from stone crusher industries. It has properties for use as partial substitute of Coarse Aggregates in concrete.

can we used aggregate crushing sand used in concrete , what effect on water cement ratio.
Sahu et al. (2003) observed that concrete made using crushed rock sand attained the comparable compressive strength, tensile strength and modulus of rupture as the control concrete. Sahul Hameed and Sekar (2009) concluded that the compressive strength, split tensile strength and the durability properties of concrete made of quarry rock dust are nearly 14% more than the conventional concrete.
