ASTM WK33418

    New Test Methods for Detecting Sulfates in Construction Soil Materials

    (What is a Work Item?)

    WK33418

    1. Scope

    This standard consists of two rapid field test methods to detect sulfates in soils. The first test method measures soil conductivity as an indicator of the presence of salts and can be used as a screening tool to identify a potential sulfate problem. The second method is a laboratory method to accurately quantify the portion of the conductivity results that are attributed by sulfates rather than by other salts. These test methods provide a means for detecting concentrations on a roadway or building site during rough and final grading as well as verification of the concentrations measured during soil explorations.

    There is currently no ASTM method for the rapid determination of sulfates in construction soil materials. Sodium sulfate causes deterioration in concrete structures. The subcommittee has been encouraged by geotechnical consultants and a government agency to develope an ASTM standard that addresses this issue.
