What are the disadvantages of m sand?


  • 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.

Why is m sand needed?

Advantages of M sand It is artificially manufactured so required property can be obtained. It does not contain impurities such as clay, silt thus increases the quality and durability of concrete. It is cheaper than river sand. It is an economical and eco-friendly material.

Which cement is better 33 grade or 53 grade and why?

Here you can see the initial strength of 53-grade cement is higher than 33 grade or 43-grade cement. The strength of 53 grade does not increase much after 28 days because of early strength gain. With time 33 and 43-grade cement will attain the same ultimate strength as that of 53-grade cement.
