Chung's "Smart Cement" was patented in 1998. The so-called "smart cement" is to add short carbon fibers to the traditional cement mixture. This improvement can use instruments to continuously "monitor" the compression and minor deformation of the cement, and when the deformation of the dam exceeds the bottom line, it will trigger an alarm. Similarly, the electrical properties of Smart Cement can be used to monitor underground pressure on buildings before an earthquake, to check for intruders in buildings or people staying during an evacuation, and to monitor traffic flow in an emergency or around the U.S. border,
Chung said.
Chung has also worked on the use of continuous carbon fibers in a composite form, suggesting that some dams could be wrapped in a shell made of the composite, similar to the material used in the fuselage of a jet aircraft. If it is used as the shell of the dam, the conductivity of the carbon fiber can be used to monitor the damage of the fiber.
According to Chung, the use of "smart cement" will reduce the cost of construction by 30%, which is the main reason for the industry to adopt this method. (Please indicate the source for reprinting by China Cement Net)
