How Much Crushed Stone Do You Need? A Sure-Fire Formula

Jul 26, 2021  Crushed Stone is a man-made construction aggregate typically produced in a quarry by passing stones through a crushing machine. (Gravel, in contrast, is produced naturally). The crushed stone is typically used as a base or underlayment, for example, where the concrete of a patio will rest. It's also used for drainage and landscaping.

The Effect of Aggregate Properties on Concrete

Crushed stone produces much more angular and elongated aggregates, which have a higher surface-to-volume ratio, better bond characteristics but require more cement paste to produce a workable mixture. The surface texture of aggregate can be either smooth or rough. A smooth surface can improve workability, yet a rougher surface generates a ...
