Durability of Lightweight Concrete. Phase III. Freezing and Thawing Tests of Lightweight Concrete
The report is primarily concerned with developing a criterion to be used in evaluating lightweight aggregates for use in structural concrete. It covers freeze and thaw resistance. The testing program covered three sources of lightweight aggregate and one source of gravel and sand. The tests consisted of subjecting specimens made from concrete mixes containing various cement contents and aggregate gradations with the moisture condition of the aggregates varied, to rapid freezing and thawing in air. In addition, complete physical tests were run on the aggregates such as, gradation, unit weight, abrasion and soundness loss. The results of this study indicate that lightweight concrete is more resistant to freezing than sand and gravel concrete. In addition, a criterion of 500 cycles of freezing and thawing in air with a loss of original modulus not to exceed 10 per cent, should be used for accepting lightweight aggregates for use in structural concrete.
