Concrete is a man-made material created by the proper mixing of coarse aggregate,such as gravel ,fine aggregate ,such as sand ,and cement ,with adequate and controlled amounts of water.Concrete is very strong in compression,and ultimate strengths of 5000psi(34.5N/mm2)to 6000psi(41.4N/mm2)can be otbtained.But concrete is very weak in tension,and so has to be adequately reinforced with steel bars .The concrete then takes the compression,and the steel takes all the tension.Both materials work together as a composite material.This material is then called reinforced concrete.
Concrete sets ,or hardens ,into a dense,stonelike substance.Unlike stone ,however,it does not have be cut and shaped into individual blocks that are then fitted together to make a wall.Instead ,it can be poured into woooden forms to make solid,one piece structures of almost any shape.

混凝土是一种由恰当混合的粗骨料,如碎石,细骨料、原砂、水泥、大量的水经过充分拌制人的造材料.混凝土具有很强的承压能力,极限承载力可达5000 psi(34.5 n /平方毫米)到6000 psi(41.4 n /平方毫米).但混凝土在张力略有不足,因此必须由钢筋充分加固.混凝土承载压力,钢筋则承载张力.两个材料作为一种复合材料一起使用.这些原料又称为钢筋混凝土.混凝土放置后,变稠变实,变成一个岩石状的物质.不像石头,它并没有被切成用来筑墙的砖块.相反,它可以灌入任何形状的木质模具中成型,.

  混凝土是一种人造材料,制作时需要按适当比例混合粗料,比如碎石,细料,比如沙子,水泥和适量的水.混凝土的抗压能力非常强,其极限强度可达到5000psi (34.5N/mm2) 至6000psi (41.4N/mm2).但是混凝土的抗拉能力很弱,以至于不得不用钢筋进行加强.于是,混凝土承担压力,而钢筋承担张力.两种材料结合在一起构成了复合材料.这种材料就被称为钢筋混凝土.
