| description | Compaction directly affects concrete’s strength and durability. In this paper, the relationship between vibration parameters and compactness is modeled by using colored aggregates and image methods to analyze the compactness of concrete characterized by pore structure. Experiments were conducted to investigate the effects of vibrating frequency and duration on the aggregate distribution coefficient, segregation rate, and porosity of slipform concrete. The test results showed that the smaller the aggregate size under high-frequency pounding, the better the concrete compactness. In addition, the aggregate segregation rate and concrete strength increased and then decreased with the pounding length, and the greater the pounding frequency, the more pronounced the trend. Lastly, the concrete’s internal porosity increased and then decreased with the pounding length. This study obtained the control range of aggregate segregation rate and porosity through analysis, and established equations for the optimal vibration parameters and paving speed of sliding form concrete to guide the reasonable control of actual sliding form paving and vibration construction processes. |
