Manufactured Sand (M-Sand) for Concrete
The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.

MANUFACTURED SAND FOR CONCRETE
Manufactured sand provides an opportunity to control the particles'' mineral content, in contrast to natural sand, which often contains undesirable minerals and clays whose effects on concrete quality can be very harmful. Another reason for using manufactured sand is the growing shortage of natural sand. The best fine material for concrete production is cubical sand made from crushed rock. The

Manufactured Sand (M-Sand) in Construction
Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Manufactured sand can contain larger amounts of micro fine particles than natural sand, This can affect the strength and workability of the concrete. We are also using M-sand for current project.

7 Types of Sand Used in Construction
But not all sand is the same as some have rocks and impurities that make them less resistant and stable for use in construction. The main types of sand used in construction range from concrete sand to pit sand, natural or river sand, manufactured sand (M-sand), utility sand, and fill sand.

Manufactured sand – a solution to the global sand
Sand may constitute between 30 and 40% of the main components of concrete – or even higher, depending on the mix design – but is has a great influence on the amount of cement required to achieve the concrete properties demanded. Here, cement will represent an average 50% of the cost of the total mix. High-quality manufactured sand will therefore not only offer benefits by improving
