混凝土是应用最为广泛的施工材料，在房屋、桥梁、公路等工程项目中与受弯构件相配合。因为混凝土具有较低的极限应变与抗拉强度，应力构件施加压力给混凝土，对荷载之后的拉力做抵消，是有效控制裂缝的方式。

Concrete is the most widely used construction materials, which is match to the flexural member in the houses, bridges, roads and other projects. Because the concrete is low in tensile strength and ultimate strain, there is an offset to loaded force when pressure happened from stress member to the concrete. It is an effective way to control the crack.
