Effect Of Fineness Of Sand On The Cost And Properties Of Concrete

Concrete is the integral part of any construction concrete consists of cement sand aggregates and admixtures mixed with water no doubt concrete is the most important construction material for any structure’s serviceability and durability but it has also a darker side when it comes to environment safety.
