    The analysis of results from freeze-thaw durability tests on concrete masonry units
    (University of New Brunswick, 1995) Blanchard, Michele A.; Bremner, Theodore; W., Bremner
    Over one-hundred and seventy-five test coupons, from lightweight and normal weight concrete masonry units, were tested according to ASTM CI262-94 "Standard Test Method for Evaluating the Freeze-Thaw Durability of Manufactured Concrete Masonry Units and Related Concrete Units." The results of these tests were analyzed to determine if any correlation existed between percent deterioration and the amount of binder, density, absorption and the strength. The objective was to see what effects mix proportions, compressive strength, and manufacturing procedures have on the durability. Suggestions are made to increase the effectiveness of the test method. Finally guidelines are given to identify appropriate pass-fail criteria for the test.
