防撞墻模具的流動性。指混凝土拌合物借助一些設(shè)備，例如振搗棒，克服內(nèi)部阻力，以及混凝土與模板、鋼筋之間的粘結(jié)力，產(chǎn)生流動并填滿模型與鋼筋周圍的能力?；炷亮鲃有院?，操作方便，易于搗實、成型，不致使混凝土成型“蜂窩”、“麻面”等現(xiàn)象。但若流動性過大，容易影響混凝土的密實性和均勻性。不同的構(gòu)件，如配筋少的薄板對流動性的要求與澆筑密集配筋的柱子大不一樣。

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
