This can be described as a sort of “chain”, starting with rock blasting in a hard rock quarry, advancing to rock crushing and screening, then continuing to a ready-mix producer, and finally ending up at the construction site, where the crushed sand concrete is to be evaluated by the end user, i.e. the contractor.

The stone''s natural color and texture is enhanced. Alternatively, different tools can be used to create a rough surface; including, chiselling, sand-blasting or heat and flame treatment. The flame treatment process allows small flakes of stone to fall off, due to the expansion of certain minerals (especially the quartz).
