钢筋与混凝土材料有着不同的局部承压强度,钢筋的局部承压强度是混凝土的20倍,说明了钢筋与混凝土材料的局部承压强度相差悬殊,可以利用这一点进行两种材料的区分,通过在钢筋混凝土构件局部表面施加一定的压力,使混凝土先行破坏,而此时的的压力远小于钢筋的局部承压强度,所以钢筋不会受其影响被破坏,此刻混凝土已经发生破坏,比较容易与钢筋奋力,再通过相关技术将两者分离,从而降低了施工的难度并且提高了钢筋的回收利用率。
Reinforced concrete materials have different local compressive strength, the local compressive strength of reinforced concrete is 20 times, indicating that the local compressive strength of steel and concrete materials vary greatly, you can use this to distinguish between the two materials, through the A certain pressure is applied to the local surface of the reinforced concrete member to cause the concrete to be damaged in advance while the pressure at this time is far less than the local bearing strength of the steel bar so that the steel bar will not be damaged by the influence and the concrete has been damaged at this moment and is relatively easy Rigid steel, and then through the relevant technology to separate the two, thus reducing the difficulty of construction and improve the recycling rate of steel.
