摘要
As a traditional and crucial phase in concrete preparation, vibration faces technological challenges due to innovative new cementitious composites and construction industrialization. This paper critically reviews the mechanism of action of fresh concrete vibration in recent publications. It elucidates the mechanistic models of rheological behavior (simplify to a power-law pseudoplastic models), energy transfer (e.g., the Dessoff formula), and internal component migration according to the Stokes theories under vibration. By characterizing the response state of concrete vibration, concrete mixtures are typically treated as particulate aggregate materials in simulations. It also summarizes the key influencing factors in vibration design, including vibration modes, time, frequency, amplitude, and location. The paper describes advanced detection methods and optimization techniques currently involved in concrete vibration to optimize the process further. This review will serve as a reference for researchers in the field and provide new insights for the future development of concrete vibration technology.
