Abstract:
The Bureau of Reclamation has proportioned roller compacted concrete (RCC) mixtures since 1979, beginning with the Upper Stillwater Dam Project. Reclamation's research and project-related RCC investigations cover a variety of structures and varying site conditions. Reclamation proportions RCC mixtures to meet both fresh and hardened concrete properties. This assures construction of high-quality concrete structures. Ongoing research has continued to identify specific properties of RCC, such as bond strength, freeze-thaw durability, and thermal properties that significantly affect the performance of these structures. Paper summarizes RCC mixture proportions and properties of fresh and hardened concrete from Reclamation's RCC research and project activities.
