| Abstract | Based on the field measurement and combined with relevant references, the different sinusoidal vibration parameters (5Hz/4mm and 20Hz/2mm) are selected and applied to new constructed concrete by vertical vibrating table and AC impedance technique. The concrete permeability is discussed, and the influences of some factors including different vibration time (before initial curdle, between initial curdle and finial curdle, after finial curdle), different vibration energy. From the experiment results, the following conclusions can be concluded. No matter whether the concrete vibrated or not, the uniformity inside the concrete along the direction of concrete pouring is shown that the upper and lower part of concrete is more discrete. The permeability on the both end of concrete is larger than the middle. The new constructed concrete permeability is increased when the vibration energy is lower, and decreased when the vibration energy is higher, and the new constructed concrete permeability affected by environment vibration obviously before initial curdle time. |
