ABSTRACT
Roller-compacted concrete (RCC) has rapidly become a commonly used material for dams and massive structures. It is also used for overtopping and erosion protection of embankments and for heavy-duty pavements. This chapter concentrates on mass applications of RCC, primarily for dams; however, many of the concepts, from testing to material properties and mix designs, apply to all uses of RCC. In a sense, RCC dams can be thought of as a series of bonded pavements or parking lots stacked on top of each
other. This chapter provides an explanation of what RCC is, how it differs from conventional concrete, what its special properties are, and how to use it effectively. The chapter covers specific technical and construction issues, including aggregates and mixture proportioning, laboratory testing, properties, engineering and design, cost, and construction. Emphasis is placed on areas of controversy and significant interest, such as cost savings, mixture proportions, material properties, watertightness, lift-joint quality, and design options.
