Embedded Ultrasonic Transducers for Active and Passive Concrete Monitoring
Recently developed new transducers for ultrasonic transmission, which can be embedded right into concrete, are now used for non-destructive permanent monitoring of concrete. They can be installed during construction or thereafter. Large volumes of concrete can be monitored for changes of material properties by a limited number of transducers. The transducer design, the main properties as well a...
متن کاملMonitoring of Crack Propagation in Concrete Using Embedded Piezoelectric Transducers
A concrete structure can be subject to several factors that may damage it during its service life. These factors are either be climatic, chemical or accidental. The security requirements are more and more speci c and severe. To ensure the safety of a structure, it is important to know its state and the properties of the materials that make it up. For this purpose, many tests has been developed....
متن کاملDesign of Embedded Piezoelectric Transducers for Structural Health Monitoring in Concrete Structures
In the last decades the field of structural health monitoring and damage detection has been intensively explored. Active vibration technique allows to excite the structure at high frequency vibrations which are sensitive to small damage. Ideal candidates for the generation of high frequency (ultrasonic) signals are piezoelectric PZT transducers, due to their small size, low cost and large bandw...
متن کاملThe Study of Active and Passive Transducers
This paper illustrates the working of active and passive transducers, their characteristics and it lights up the theoretical study with its application. This thesis focuses the real world use of active and passive transducers with their major types of classifications.
متن کاملResearch on Embedded Sensors for Concrete Health Monitoring Based on Ultrasonic Testing
In this article, embedded ultrasonic sensors were prepared using 1–3-type piezoelectric composite and piezoelectric ceramic as the piezoelectric elements, respectively. The frequency bandwidth of the novel embedded ultrasonic sensors was investigated. To obtain the relationship between the receiving ultrasonic velocity and compressive strength, as well as their response signals to crack damage,...
