The granite and melaphyre aggregate showed similar characteristics of the fine fraction curve, albeit above 15 mm the grains of granite were coarser. The content of fine particles, which are decisive for the quality of the produced aggregate, is an important parameter of this construction material.

The values obtained are in the ranges specified in [23, 28, 29]. The coarse aggregates are irregular in shape. The fine modulus of fine aggregate is 5.27 and that of coarse aggregates (Igneous rock – crushed granite stone, sedimentary rock- limestone and metamorphic rock- marble stone) are 7 2.38, 2.07 and 4.16 respectively.

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.

A large number of projects have been executed either with crushed coarse aggregates or with gravel. Similarly, it is true for natural as well as crushed sand. The engineer has to understand that if the parent materials i.e. Basalt or granite are the same then there is absolutely no harm in using it either in a natural or crushed form so long as it is free from deleterious materials.

$\begingroup$ You seem to be considering "crushed gravel" as a blend of coarse and fine aggregate. I don''t believe that is correct in general, but in the particular text referenced by @hazzey, it states that "the fine aggregate shall be produced by crushing stone, gravel or slag that meet the requirements for wear and soundness specified for coarse aggregate."
