Concrete components are generally assembled through wooden or steel formwork and then cast and shaped. The formwork is designed to place steel bars, and then concrete composed of fine aggregate, coarse aggregate, and cement (cementitious material) is poured into the formwork. During the pouring process, in order to allow the concrete to fully penetrate into every corner of the formwork and tightly wrap the steel bars (some components do not require steel bars to be cast), vibration is generally required. Some formworks are also equipped with penetrating crossbars to cooperate with pouring to strengthen the components.
