ASTM WK42497

    New Test Method for Determining the Presence of Expansive Clays in Rock for Erosion Control Using Ethylene Glycol

    (What is a Work Item?)

    Developed by Subcommittee: D18.17 | Committee D18 | Contact Staff Manager


    1. Scope

    This method is a procedure for immersing rock for erosion control in ethylene glycol and the observation of the effects of such immersion.

    Potentially deleterious clays can be found in rock for erosion control. The industry does not have a current procedure to determine the presence of such clays. To serve the erosion control industry, it is in ASTMs best interest to develop a standard test procedure to address this situation.


    Swelling clays, montmorillonite

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