WHAT IS THE IMPORTANCE OF AGGREGATE

2014-6-25  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. So we can definitely say that, most of the requirement of concrete in its plastic state is affected by aggregate properties and, “ gradation of aggregate” is one of them.
