Abstract:
A method was developed which would permit the placing of extremely long monoliths of mass concrete without the occurrence of excessive tensile stress from cooling. Th e method is to maintain a low temperature of the surface concrete during hardening. Thus, com- pressive stress is produced when the surface warms, and subsequent cooling does not cause high tensile stress. The basic concepts of this method are described, detailed computations of stresses are given, and possible construction methods for accomplishing the reduced temperature are suggested.
