Natural or River sand are weathered and worn out particles of rocks and are of various grades or sizes depending upon the amount of wearing.
Advantages of Manufactured Sand (M-Sand) It is well graded in the required proportion. It does not contain organic and soluble compound that affects the setting time and properties of cement, thus the required strength of concrete can be maintained.
Natural sand does not require more water to enhance the workability of the mixture so the amount of bleed water in the concrete will not be increased. Manufactured sand or manufactured fine aggregate (MFA) is produced by reducing larger pieces of aggregate into sand-sized aggregate particles.

The price of manufactured sand can also be lower compared with natural sand, which decreases the production cost of the concrete even further. If we consider the fact that natural sand sources are getting scarcer, especially close to urban areas, transportation costs can be considerable if the sand has to be transported with trucks from tens of kilometers away.
manufactured sand (M-sand) instead of natural river sand in making concrete. M-sand is obtained by crushing the natural granite stone in the vertical shaft Impact crushers and screening the output form the fine aggregates of size less than 4.75mm. Some studies has been reported the effect of M-sand on strength and durability properties of

More and more, GCP Applied Technologies' scientists and technical experts have observed the use of manufactured sand over natural sand, as a fine aggregate in ready-mixed concrete. THE PRIMARY REASON: Environmental concerns have made what remains of available natural sand resources an economically unviable option for the concrete producer.
concrete whereas manufactured sand has no silt or organic . impurities [2]. In general, the demand of natural sand is quite . high in developing countries to satisfy the rapid infrastructure .
Sand – whether extracted from natural gravel or sand deposits or made by crushing bedrock – is used in many applications because of its mineral and physical qualities. The most typical application for sand is concrete, where it accounts for approximately 30–40% of the material volume.
In order to bring all the involved parties together to solve the challenges, COIN, Concrete Innovation Centre (www.coinweb.no), was founded in 2006. Since 2009, Metso has been an active and key participant in the COIN project “High-quality manufactured sand for concrete”.
Answer is affirmative. Yes certainly it's possible. It's feasible to replace the river sand with the crushed sand or artificial sand or M sand. In fact that's what the RMC plants are already doing. Design mix involves careful study of the study of...
