Includes descriptive matter and tests on. the cause and control of cracking, temperature variation and thermal stress and volume change, based on des ign and research work of the Bureau of Reclamation. Structures studied include Owyhee, Boulder, Grand Coulee, Norris, Bartlett, and Morris dams and other smaller dams. Shrin kaqe studies of test bars and cylinders are described and results indicated. The most effective single method for improving crack- ing conditions is the use of low-heat or portland- pozzolan cement.
