WK30854 Revision of C856 - 04 Standard Practice for Petrographic Examination of Hardened Concrete

1. Rationale

The Paste Features section 12 contains only a small section on w/c and w/cm. The subcommittee has agreed that this section should provide the petrographer with guidelines for estimation of w/c and w/cm. To achieve this goal, the section has been expanded and will be balloted as an appendix to C856.
