• Abstract:

  This report covers tests performed to evaluate the durability of lightweight concrete when subjected to repeated cycles of wetting and drying. The work described in this report is one phase of a three phase project dealing with durability of lightweight concrete.Phase I and III are described in the report on Phase III which has been completed and the results reported. Phase I is expected to be completed during 1967 and the results will be reported as soon after completion as possible.
  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 repeated cycles of wetting and drying. In addition, complete physical tests were run on the aggregates such as, gradation, unit weight, abrasion and soundness loss.
