ASTM WK44458

    New Test Method for STANDARD TEST METHOD FOR MEASURING THE SULFATE RESISTANCE OF HYDRAULIC CEMENTS (MINI-BAR TEST)

    (What is a Work Item?)

    WK44458

    1. Scope

    1.1 This test method provides a means of assessing the sulfate resistance of hydraulic cement and blended hydraulic cement by measuring expansion after immersion in a sodium sulfate solution bars 10 mm x 10 mm x 60 mm [0.4 in x 0.4 in x 2.4 in] after curing for 7 days at least.

    The current test to determine the sulfate resistance of cement (ASTM C1012) requires at least 1 year of testing. The new proposed test requires only 3 months, providing a test result consistent with that of C1012. This method is suitable to evaluate the effectiveness of portland, hydraulic cements as well as blended hydraulic cements, for resistance to sulfate exposure. The test is simple and while it uses special molds, the expansion can be measured using the C1012 comparator with minor modifications.
