ASTM WK85519

Revision of C94/C94M-22a Standard Specification for Ready-Mixed Concrete


Section 6.7 requires a certified copy of proportions be stored on file at each batch plant. Mixture proportions are now stored in a software database, usually in a remote data center, and synchronized with the batch plant at or before the order. Therefore, it is no longer necessary to have a certified copy in the batch plant.
