Steel bar corrosion monitoring is a very important part of structure health monitoring and full-life design in civil engineering.
Introduction The deterioration of concrete infrastructures is one of the greatest civil engineering challenges facing the developed world.
The working electrode is Q235 carbon steel which is wildly used in civil engineering.

High-quality engineering materials technology training is in engineering materials technology development to protect.
All of the above reasons lead to students lack of the ability to solve practical engineering problem and lack of the modern engineering knowledge about economy and society that they have to know; Third , separated theoretical study of engineering materials and engineering materials applications personnels cultivation lead to the separation of engineering materials research and practice.
Engineering and technical personnel need to keep new demands on engineering materials, engineering, materials scientists also need to continue to develop new materials, which requires engineering materials research and engineering technical personnel to master the new direction of development of science and new developments.

Introduction Civil infrastructure is exposed to a multi-hazard environment including extreme windstorms and strong earthquakes.
The friction dampers utilize their sliding mode to accommodate large deformations in civil engineering structures and use piezoelectric actuators to regulate their clamped force.
In civil engineering, the main goal is trying to extract energy from structural vibration that can be used to power wireless sensors.
Scruggs et al. [6-7] are the first to suggest the active control with the harvested vibration energy in the area of civil engineering.
