Since the advent of nano-materials, its unique mechanical properties and chemical properties has been the concern of many experts and scholars. Describes the application of research results in recent years and nano-materials in the construction industry. Adding nano-materials in ordinary concrete can improve the performance of concrete including strength, toughness, durability and other properties. In recent years, with the increase in the number of nano-materials researchers, nano-materials we use in the construction industry also have a better understanding, but not yet fully grasp its mechanism of action. So we need more in-depth research and exploration.
