Fractured aggregate is defined as an angular, rough, or broken surface of an aggregate particle created by crushing, or by other means. A face is considered a fractured face whenever one-half or more of the projected area, when viewed normal to that face, is fractured with sharp and well-defined edges this excludes small nicks.

Exposed Aggregate (surface retarder) This process uses a chemical surface retarder which is applied onto the forms prior to casting. The chemical retards the set of the cement so that it may be removed (usually by water blasting) the next day. This results in exposure of the aggregate while preserving its natural beauty and texture.
