一、问题的提出混凝土通常是用振动方式来捣实的。但由于对振动情况下新浇混凝土的运动情况缺乏了解,因此用于混凝土捣实的能量大大超过其捣实所必须的能量。据索耳(Saul)的估计,由于混凝土混合料的摩擦,振动器的能量损失达到90％。如果使这些能量损失减少到80％,则用于混凝土捣实的有效能量将大为增加。苏吉切(sugicuhi)所著的关于混凝土振动的文献评论谈到,对振动情况下新浇混凝土性能的解说已难以进行理论分
First, the issue of the proposed concrete is usually vibrated. However, due to the lack of understanding of the movement of freshly poured concrete under vibration, the energy used for concrete compaction greatly exceeds the energy necessary for its compaction. According to Saul’s estimate, the vibrator’s energy loss reaches 90% due to the friction of the concrete mix. If these energy losses are reduced to 80%, the effective energy for concrete compaction will increase significantly. Sugicuhi’s literature review on concrete vibrations mentioned that it is difficult to theoretically explain the performance of freshly poured concrete under vibration conditions.
