Nowadays,

We should start to use M-sand as one of the alternative building construction material so that impacts on the environment will get reduced to some extent.

Here, I will be discussing some advantages and disadvantages of manufactured sand.

Advantages of manufactured sand :

• Manufactured sand has a higher fineness modulus index as compared to natural sand
• It has better abrasion resistance because manufactured sand is free from silt and clay.
• Lower Permeability
• Higher unit weights
• It has very less destructive to our environment because it highly reduces sand mining from the river bed.
• It has good workability of concrete
• Higher-strength
• Greater durability.

Disadvantages of manufactured sand:

• Higher cost
• More requirement of water-cement due to its smooth and angular texture to achieve appropriate workability.
• Presence of more amount of micro-fine particles that adversely affect on strength and workability of concrete.
