混凝土振捣混凝土振捣是指用振动机械的振动力提高混凝土密实程度的过程。混凝土拌合物在振捣时,内部粘着力和摩擦力显著减小,使混凝土拌合物由原来很稠的状态暂时转变为有一定流动性的液体状态。因此,骨料在重力作用下下沉,排列紧密,水泥砂浆填满了所有的空隙,气泡排出,从而提高了混凝土的密实度。振动机械可分 Concrete vibrating concrete vibrating refers to the process of improving the compactness of concrete by using the vibration force of vibrating machinery. When the concrete mix is ​​vibrated, the internal adhesive force and friction force are significantly reduced, and the concrete mix temporarily changes from a very thick state to a liquid state having a certain fluidity. Therefore, the aggregate sinks under the action of gravity and is tightly packed. The cement mortar fills all the voids and bubbles are discharged, thereby increasing the compactness of the concrete.
