Self-consolidating concrete (SCC) is an innovative type of concrete technology with significantly enhanced fresh properties that eliminates the need for mechanical vibrations. SCC is characterized by its ability to flow through structural elements under its own weight, filling every corner of the formwork, even in the presence of congested steel reinforcement. Currently, the Nevada Department of Transportation (NDOT) uses SCC mainly for casting drilled shafts. Several federal agencies are currently promoting the expansion of SCC use for all the advantages it provides. This project has two folds. The first fold is sponsored by NDOT where the effects of concrete pumping, tremie use, form shape, local aggregate properties, casting height and/or reinforcement congestion would be investigated. The first fold will conclude with proposing different mixes to be used by NDOT for SCC applications. The second fold will be sponsored by Missouri University of Science and Technology NUTC. The second fold will investigate the cyclic behavior of SCC and will be compared to cyclic behavior of conventional concrete. |
