ASTM WK70863

    New Practice for Petrographic Examination of Hardened Cement-Based Construction Materials

    (What is a Work Item?)

    Developed by Subcommittee: C09.65 | Committee C09 | Contact Staff Manager


    1. Scope

    This practice outlines procedures for the petrographic examination of hardened concrete and other cement-based construction materials. The materials may be from construction elements, pre-fabricated products or portions thereof, or test specimens exposed to natural environments, simulated service conditions or laboratory tests. The practice applies to materials created with hydraulic cement or other cement-based binder, and employs the use of varied microscopic techniques and supplementary analytical tools for the mineralogical and microstructural characterization of the material components.


    Polarized light microscopy; scanning electron microscopy; petrographer; mineralogy;


    The rationale for this ballot is to modernize completely the existing standard practice for petrographic examination of hardened concrete by re-organizing and re-formatting the existing, dated standard (ASTM C856) and merging practices and procedures for optical and electron microscopy (ASTM C1723) into a single cohesive document.

    The title and scope are in draft form and are under development within this ASTM Committee.
