Abstract:
The practice of the United States Bureau of Reclamation is to build large dams in blocks bounded by keyed joints to minimize cracking caused by shrinkage which is due to dissipation of the setting heat of the concrete. After the concrete reaches its minimum temperature the voids in the joints between the blocks are filled with cement grout under pressureto create a concrete monolith. This paper describes experiences in the development of the present grouting techniques and the actual process of grouting contraction joints in large concrete dams. Special reference is made to grouting at Shasta Dam.
