混凝土作为重要建筑材料之一,人们对其性能的要求越来越高。而混凝土结构自身存在着一定的缺陷,如脆性大、易产生裂缝等,这些都严重影响着混凝土的使用性能。形状记忆合金作为新兴的功能材料,其形状记忆性能以及形变恢复时所产生的强大应力等特点恰好能弥补水泥混凝土自身的一些不足。因此,将形状记忆合金应用于水泥混凝土中,以改善水泥混凝土性能的研究与应用已广泛的开展,并取得了良好的效果。
Concrete as one of the important building materials, people’s requirements for its performance are getting higher and higher. The concrete structure itself has some defects, such as brittle, easy to produce cracks, which are seriously affected the performance of concrete. Shape memory alloy as a new functional material, its shape memory properties as well as the strong stress generated by deformation and other characteristics just to make up for some of the shortcomings of cement concrete itself. Therefore, the shape memory alloy used in cement concrete to improve the performance of cement concrete research and application has been widely carried out, and achieved good results.
