Abstract:
Mass concrete placed by the Corps of Engineers differs from most structural concrete in at least two important respects: (1) strength of the concrete is not involved in contractural relations between the bidder and owner; and (2) in most cases strength of the concrete is not critical since tests are made on a regularly scheduled basis and are analyzed by the methods of ACI 214 in order to assess the adequacy of control and, in the case of the few very high structures, to determine whether the average strength is sufficiently high to assure a .08 probability of attaining the stipulated strength.
