WHAT IS THE IMPORTANCE OF AGGREGATE GRADATION IN CONCRETE ...

Importance in terms of Workability. A workable concrete can be achieved by adding more water, but as we know the more water present in concrete the poor strength it gives. The most efficient way to achieve workable of concrete is by adopting a good gradation of aggregate. Also aggregate comprises 85% of the volume of concrete.
