Book Description
The use of no-slump, roller-compacted concrete (RCC) in mass concrete construction was investigated. RCC is concrete having no slump but containing the minimum amount of water necessary to achieve consolidation with a vibrating roller. Tests were conducted to: (a) optimize mixtures for application of no-slump techniques, (b) develop a consistency and quality control technique, (c) determine methods of improving hardened lifts joints, (d) determine the relative frost resistance of RCC, (e) evaluate the erosion susceptibility, and (f) discover economical methods of obtaining void-free vertical surfaces. Indications are that: (a) the curb concrete is viable method of forming and containing RCC; (b) the degree of compaction achieved is dependent on the stiffness and the paste content of the mixture, the lift thickness, and the individual roller; (c) the tensile strength of the untreated joints increased with paste content and quality from approximately 25 percent for relatively lean RCC to approximately 50 percent for richer RCC; (d) erosion resistance at 35-ft/sec fluid velocity of RCC is good; (e) resistance to freezing and thawing of the RCC is poor, apparently due to a poor air void system; and (f) surface treatment with a mortar gun (shotcrete) appears to be a practical method to achieve smooth vertical surfaces.

Book Description
Roller compacted concrete (RCC) is discussed in this special technical publication for the first time. The widespread use of RCC has occurred in the period since publication of the last version of ASTM STP 169B in 1978. Initial development, in the 1970s, was focused primarily on mass concrete for construction of locks and dams. In the 1980s, RCC was adapted for use in construction of pavements and other types of horizontal structures. Recently, in the 1990s, it has been applied as a repair technique to several types of structures.

Book Description
Roller compacted concrete (RCC) represents a major advance in dam-building technology. The RCC method speeds construction & reduces the costs of building without compromising safety. This work focuses on the cutting edge of RCC design technology, describing the costs & benefits of a variety of technical approaches, & offering an extensive survey of completed RCC dams & the participants involved in building them.
