通常认为结构物的耐久性不足是施工操作不当的责任。然而现代混凝土结构过早劣化的事实说明人们没有对混凝土技术中控制开裂的基本原理给予足够的重视。为了建设在环境中可持久的结构,必须变革我们的建造实践。 It is generally assumed that the lack of durability of the structure is responsible for improper construction practices. However, the fact that modern concrete structures deteriorate prematurely shows that people do not pay enough attention to the basic principles of cracking control in concrete technology. In order to build sustainable structures in the environment, we must transform our construction practices.
