What Are Aggregates and How Are They Used?

Crushed aggregates make up for around 60% to 75% of the volume of concrete. These crushed aggregates significantly affect the properties of freshly-mixed and hardened concrete – making it more compact, decreasing its permeability (which makes it more water-resistant), and modifying its heat retention values.

At a given water ratio, within the range employed in most structural concrete, smaller maximum sizes of aggregate will tend to produce higher concrete strengths than larger ones. 2. The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower water-ratio than the smaller sizes. 3.
