Abstract:
Presents a discussion of certain characteristics of mass concrete which have assumed increased im-portance in recent years by reason of more rapid construction with modern equipment of extremely large concrete dams. Understanding of the factors affecting the temperature and the thermal stresses of mass-concrete structures is necessary if advantage is to be taken of control measures t o prevent un- favorable conditions. Some of the more important factors are presented which combine to establish controlling conditions of temperature, volume change, and crack development. A section on temperature computations is included which presents methods of evaluating the effects of imposed conditions and of determining the nature and extent of the temperature control required.
