Title: Application of Roller-Compacted Concrete for Rehabilitation of Dams
Author(s): T. C. Liu and J. E. McDonald
Publication: Special Publication
Appears on pages(s): 399-416
Keywords: concrete (roller-compacted); hydraulic cement; strength
Abstract:Roller-compacted concrete (RCC), because of its superior properties, Synopsis: low cost, rapid and relatively simple construction methods, and proved performance, has been used extensively in recent years in rehabilitation projects at existing concrete and earth and rockfill embankment dams and related hydraulic structures. These applications include increasing the existing spillway capacities, construction of new service and emergency spillways, overtopping protection, and seismic strengthening. This paper presents case histories of selected applications of RCC in rehabilitation of dams and related hydraulic structures. These case histories are presented to show the range of previous applications and to illustrate typical design and construction practices in repair and rehabilitation of dams with RCC. For each of the case histories presented in this paper, an attempt is made to discuss (a) the description of the project, (b) the cause and extent of the deficiency that necessitated rehabilitation, (c) design details, (d) RCC mixture proportions, (e) description of materials, equipment, and placement procedures, (f) cost, and (g) RCC performance to date.
