Abstract: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… Show more
