Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

What is M Sand?

What is M Sand?

+

Thus m sand requires more water and cement requirement to achieve the expected workability leading to increased costs. The Other disadvantages of M sand are that m sand contains larger amounts of microfine particles than natural sand going to its production process. this again can affect the strength and workability of the concrete.

Concrete is a building material made by mixing cement paste (portland cement and water) and aggregate (sand and stone). The cementpaste is the "glue" which binds the particles in the aggregate together. The strength of the cementpaste depends on the relative proportions of water and cement; a more diluted paste being weaker.
