    About the Course

    This test method covers the testing of aggregates to estimate their soundness when subjected to weathering action in concrete or other applications. This is accomplished by repeated immersion in saturated solutions of sodium or magnesium sulfate followed by oven drying to partially or completely dehydrate the salt precipitated in permeable pore spaces. The internal expansive force, derived from the rehydration of the salt upon re-immersion, simulates the expansion of water on freezing. This test method furnishes information helpful in judging the soundness of aggregates when adequate information is not available from service records of the material exposed to actual weathering conditions.

    This course will take about one hour to complete.

    Learning Outcomes

    By the end of this course you will be able to:

    • Identify the apparatus and related components used in this test method
    • Recognize the steps to prepare the special solutions required for this test method
    • List the requirements for fine and coarse aggregate samples
    • Recognize the steps for preparation of test sample
    • Recall the procedures for the testing of aggregates to estimate their soundness
    • Recall the steps for making quantitative and qualitative examinations of test samples
    • Identify the reporting requirements for this test method


    Anyone who runs the C88 test method or who needs an understanding of the test method and how it is properly run.
