防撞墙模具的流动性。指混凝土拌合物借助一些设备，例如振捣棒，克服内部阻力，以及混凝土与模板、钢筋之间的粘结力，产生流动并填满模型与钢筋周围的能力。混凝土流动性好，操作方便，易于捣实、成型，不致使混凝土成型“蜂窝”、“麻面”等现象。但若流动性过大，容易影响混凝土的密实性和均匀性。不同的构件，如配筋少的薄板对流动性的要求与浇筑密集配筋的柱子大不一样。
Fluidity of anti-collision wall mold. It means that the concrete mixture overcomes the internal resistance and the bonding force between the concrete and the formwork and reinforcement with the help of some equipment, such as vibrator, to produce flow and fill the space around the model and reinforcement
Ability. The concrete has good fluidity, convenient operation, easy tamping and forming, and does not cause the concrete to form "honeycomb", "pitted surface" and other phenomena. However, if the fluidity is too large, it is easy to affect the compactness and uniformity of concrete. no
For the same members, such as thin plates with less reinforcement, the requirements for fluidity are very different from those for columns with dense reinforcemen
