Experimental Study on Vibrating Compaction of Extremely Stiff Consistency and Lean Mix Concrete

compaction Mechanism是根据在振动过程中发现的每个常量材料的垂直运动的混合分析测试结果在棱镜specimen中混凝土。水混凝土比率W/C和空气含量都是突出的，因为重要的内部成分因素影响了机械性能，以及参数（W/C+k·a）和压缩强度之间的关系。Furthermore，由于compaction的程度可以通过参数来评估，这是一种质量特征的适用性。它被设计为compact factor CF，以及CF和compacting conditions之间的关系，如振动器重量、振动频率、幅度和规格大小。

The compaction mechanism was examined based on the vertical movements of each constituent material which were found by mix analysis test results of concrete in prismatic specimen during the vibrating process. Both water cement ratio W/C and air content a were pointed out as the important internal composition factors influencing on mechanical properties, and the relation between a parameter (W/C+k・a) and compressive strength was obtained. Furthermore, since the compaction degree could be evaluated by the parameter, this was applicable to compaction control as a quality characteristic. This was designated as compaction factor CF, and relations between CF and compacting conditions such as vibrator weight, vibrating frequency, amplitude and specimen size were examined.
