The coarse aggregates act like bone in concrete. If we use low quality aggregate in concrete mix, the strength of concrete will be low. The amount of aggregate greatly affects the properties of hardened concrete. Increasing the amount of aggregate at a constant cement content reduce the concrete strength. Strength of concrete can also be affected by the type of aggregate. Such as, angular and rough surface concrete increase the concrete strength.
Aggregates typically make up about 60 to 75 percent of the volume of a concrete mixture, and as they are the least expensive of the materials used in concrete, the economic impact is measurable. In addition, the use of aggregates provides volume stability to the hardened concrete. The shrinkage potential of a cement paste is quite high when compared to the aggregates. Controlling shrinkage of the concrete material is important since shrinkage and cracking potential increase together.
