摘要

This study presents an investigation on the mixing efficiency of Resonance Acoustic Mixing (RAM) Technology using ultra-high performance concrete (UHPC). In the first part, RAM is optimized through acceleration curve profiles, specific mixing energy, and workability spread flow tests. In the second part, RAM is compared with a regular table top paddle mixer with regards to its effects on workability and flow, as well as, compressive and flexural strength properties. For the UHPC used in this study results showed that: 1) RAM was a viable mixing technology for UHPC, and 2) RAM produced samples of reduced rheological properties, but increased mechanical properties compared to a table top paddle mixer.
