It can be gritty, flaky, and full of filler*, or it can be well.
Suppliers were asked to supply samples from sources in the condition in which the manufactured sand product is supplied from the quarry to the concrete producer. This research project did not investigate the properties of the final concrete fine aggregate blend. It was targeted at determining the properties of manufactured.
