    Developed by Subcommittee: C09.40 | Committee C09 | Contact Staff Manager

    Rationale

    The addition of references to ASTM C1697 and ASTM C1797 is an extension of work performed under the umbrella of Committee C09. Both documents, after rigorous debate have been approved by Committee C09 for use in concrete. Addition to ASTM C94 will formalize this approval process and facilitate inclusion of these materials in concrete mixtures. The use of blends of SCMs and calcium carbonate are already indirectly referenced in C94 through C595/C595M in Type 1L and Type 1T blends. The addition of direct references will make it clear that that SCMs can be blended separately from cement and calcium carbonate and mineral fillers can be utilized by concrete producers directly.
