Different Types & Sizes of Aggregate for Concrete
Gravel or Graded stone, is another coarse aggregate suitable for concrete mixes. Gravel is formed of rocks that are unconnected to each other. Gravel is composed of unconsolidated rock fragments that have a general particle size range and include size classes from granule to bouldersized fragments.

2019122&ensp·&enspGravel, also called graded stone, is another coarse aggregate suitable for concrete mixes. Sand is the finest aggregate. It comes in different gradations: sharp sand, builder's sand, and kilndried silver sand, which vary from coarsest to finest, respectively.

Aggregates cement
Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.

Effect of Recycled Coarse Aggregate on Concrete Properties
Moreover, the discussion about recycled aggregate usually correlate with recycled coarse aggregate. Coarse recycled concrete aggregate (RCA) is produced by crushing the demolition waste of at least 95% by weight of concrete, and having a total contaminant level typically lower than 1% of the bulk mass.
