Concrete is characterized by strong compressive strength, but is relatively weak in tension and shear. It can support large axial loads, and is used extensively in the foundations of large structures such as bridges and tall buildings.but it breaks easily under bending without reinforcing steel. Concrete with compressive strength of 3,000 ~ 6,000 pounds per square inch (psi) is common.
The American Concrete Institute defines any concrete over 6,000 psi as high-strength concrete.
For structures that require flexural strength for resistance to bending moments, reinforcing steel--rebar--is embedded in the concrete. In some cases,tensioned cables are placed in the concrete to make prestressed or post-tensioned concrete. The tension to resist the bending moment comes from the reinforcing steel or the stressed cables.
For a concrete mix to reach its ultimate strength, a long period of time is needed. The ultimate strength of concrete and its 28-day strength are not t

很简单的一段翻译，太懒了:( 感觉我。。。。。。
keli1987好像不是土木工程专业的吧

混凝土材料特点是抗压能力强，抗拉和抗剪切能力差。能够承受很大的轴向压力，能够广泛的应用与桥梁和高层建筑的基础。但是如果不加钢筋，其很容易破坏。混凝土一般具有3,000 ~ 6,000psi抗压强度。（1psi=0.069公斤=6900Pa）
