Zhong Duanling (Deborah D.), a world-class expert on nanomaterials, came to China to participate in the academic exchange of "Science and Technology Week". L． Chuang has extended the improvement of building materials to intelligence.
Zhong Duanling said that she added carbon nanofibers with good conductivity to concrete, and made a surprising discovery: the complex of carbon nanofibers with good conductivity and concrete began to be "full of wisdom"!
The principle is that when the stress on the composite changes, its conductivity will react regularly. That is to say, the change law of stress on concrete can be obtained by analyzing the change law of conductivity.
Zhong Duanling said that the results of the ongoing intermediate test to simulate road conditions show that when the load on the road surface changes, the contact effect between carbon nanofibers and the surrounding matrix will also be affected, resulting in a slight change in the conductivity of composite materials. As a result, a series of important data such as weight, temperature, vibration, vehicle speed, personnel flow and damage degree are obtained.
Zhong Duanling said that the application of "intelligent concrete" is far from being limited to roads. It can be used as a structural material and widely used in highways, bridges, reservoirs, dams, buildings, residential buildings and security facilities. At the same time, it can be used as a new and multi-functional material for automatic monitoring systems such as anti-theft, seismic control, energy saving, traffic control and dynamic vehicle weight testing.
