Abstract : In the first phase of the investigation, five low cement content mass concrete mixtures containing crushed limestone aggregate graded up to the 6-in. size and having nominal air contents ranging up to 12% in the portion of the mixture passing a 1-1/2-in. sieve were made and tested to determine if the 4 to 7% air content range stipulated by current Corps of Engineers 'Standard Practice for Concrete and Standard Guide Specifications for Concrete' is optimum. In the second phase, fifteen additional mixtures were systematically proportioned and tested.
