ASTM C744
Full Name
ASTM C744 – Standard Specification for Prefaced Concrete and Calcium Silicate Masonry Units
Scope
This specification covers prefaced concrete and calcium silicate masonry units with the finished face(s) covered at the point of manufacture with resin, resin and inert filler, or cement and inert filler to produce a smooth tile-like surface feature.
This specification does not address, and therefore is not applicable to, ground-face concrete masonry units that are manufactured by grinding a thin layer off the surface of a concrete masonry unit to expose aggregates within and polishing to produce a smooth, architectural finish.
