Abstract : Twenty-four 4-in.-diameter concrete cores, three 6- by 12-in. concrete cylinders, and samples of fine and coarse aggregates were examined to determine the cause of heavy surface scaling which occurred in some of the concrete in the family housing area of the U. S. Military Academy, West Point, New York. Air content and cement content determinations, and petrographic examinations were made on the cores from the family housing area. Air content determinations were made on the cores and cylinders from the other areas. These examinations yielded evidence that supported the hypothesis that the deterioration of the affected concrete was caused by freezing and thawing which produced damage because the concrete was not air-entrained.
