Demand for river sand which is used as fine aggregate in concrete for construction works is increasing day by day. On the other hand, the metal casting industries in India produces nearly 1.71 ...

Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. The minimum permissible silt content is 3%. Anything more than 3% is harmful to concrete durability. We can expect 5 - 20% slit content in medium-quality river sand. Over-Sized Materials.

M-sand is a substitute of river sand for concrete construction. Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm.

River-sand or natural-sand has better texture, is smooth and round in shape with extremely low 'silt' and 'clay' content. 'Silt' is super fine material that is not good for construction. 'River sand' contains very less of silt making it an ideal raw material for construction. Similarly, 'clay' does not allow cement to bond ...

The natural sand deposits are being exhausted and severe environmental damage is accruing [3]. So an opportunity needs to be discovered out, the appropriate alternative is Robo Sand for river sand [4], [5]. Cement is one of the important material in construction which accounts for 8 to 10% of total CO 2.

The concept of M sand vs Robo sand now starts with the idea. M sand is synthetic sand made by crushing huge hard stones, primarily boulders or granite, into fine particles, washed and finely graded. It is frequently used in construction to substitute river sand, mainly in preparing concrete and mortar mix. The manufacturing process of M sand

Unavailability and shortage of natural sand can also be balanced by using crushed stone. Manufactured sand is also known as crushed sand and stone dust and it is made by crushing and grading suitable granite stones and rocks. As we all know that river beds are used to obtain natural sand. Now the depletion of natural sand has become a very big
