Significance of aggregate grading ConcreteBasics ...

Aggregates having a smooth grading curve and neither a deficiency nor excess of any one particle size will generally produce mixtures with fewer voids between particles. Since cement costs more than aggregate and the cement paste requirement for concrete increases with increasing void content of the combined aggregates, it is desirable to keep the void content as low as possible.

Why Aggregates have an Important Role in

Aggregate’s impact on different characteristics and properties of concrete is certainly huge. Properties of concrete include workability, durability, strength, weight and shrinkage. An aggregate provides body i.e. volume/mass of the concrete, reduces shrinkage and also help to achieve economy.

WHAT IS THE IMPORTANCE OF AGGREGATE

25-06-2014  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.
