Aggregate particles larger than 4.75 mm are visually examined to determine the percentage of particles that has at least one fractured face, and the percentage that has at least two. A CAFF value of 76/53, for example, means that 76% of the particles in a coarse aggregate have at least one fractured face, and 53% have at least two fractured faces.

ARCHITECTURAL CONCRETE MASONRY UNITS - NCMA

Split faced units have a natural stone-like texture produced by molding two units face-to-face, then mechanically splitting them apart after curing, creating a fractured surface. Because coarse aggregate is also fractured and exposed in this process, aggregate selection can alter the final appearance.
