Title: Freezing and Thawing Tests of Lightweight Aggregate Concrete
Author(s): Paul Klieger and J. A. Hanson

Abstract:Nine lightweight aggregates and one natural sand and gravel aggregate were used in concretes subjected to laboratory freezing and thawing tests and in some cases, to tests for resistance to deicer scaling. Concretes were prepared at two levels of compressivs strength: 3000 psi and 4500 psi at 28 days. Both non-air-entrained and air-entrained concretes were prepared, using the aggregates in on air-dried condition and in a 24-hr saturated condi-tion. The results of these tests indicate the necessity for providing intentionally entrained air to attain a high level of durability, the importance of moisture content of aggregate and then influence of strength level, water-cement ratio, on the durability. The results point to the desirability of evaluating a lightweight aggregate by means of laboratory freezing and thawing tests of air-entrained concrete made with the aggregate, as is gen-erally done for normal weight aggregate.
