What is Crushed Aggregate? (with pictures)
For example, although the larger, coarse crushed aggregates are more economical, this type of aggregate can present problems if used in concrete forms for upright structures. By comparison, fine aggregate is suitable for use in concrete, but it would not be a recommended choice for the creation of a roadbed or driveway.

Influence of natural coarse aggregate size, mineralogy and water
Natural coarse aggregates (crushed-stone) can be obtained from different type of rocks, mainly granite, calcareous, basalt and marble. Aggregates for concrete production, occupy 70–80% of its volume, where coarse aggregates are the larger part of about 2/3 of total volume of aggregates.
