Abstract:Tests were made in the field to determine the effect of age of concrete, at the time of the first application of deicing salt, on the resistance to frost and salt action. Slab specimens, 36 x 36 x 6 in., were provided with dikes which permitted the freezing of approximately 3/8 in. of water on their surfaces. Specimens were made with Types I and IA cements and a blend of the two cements, which yielded concretes having air contents of approximately 1.5, 3.0, and 5.0 percent. Ice was removed by applications of flake calcium chloride whenever the 3/8 in. of water was frozen solid. A total of 55 cycles of freezing and thawing were obtained in the one winter. Except for the specimens which were 117 and 91 days, respectively, at the first freeze, those made with concrete containing approximately 1.5 percent air were completely scaled in from 5 to 15 cycles of freezing and thawing. Complete scaling was obtained in less than 55 cycles of freezing and thawing with the concrete containing approximately 3 percent air only on specimens which were 29 days old or less at the time of the first freeze, and with concrete containing approximately 5 percent air only on specimens which were 8 days old or less at the first freeze.
