Smart Hybrid Multifunctional Nano Composite Concrete Embedded Sensor for Structural Health Monitoring Applications

Abstract

Structural health monitoring (SHM) process plays a significant role in civil engineering newlinestructures to ensure the safety, reduces the maintenance cost and increases the service life newlinespan of them. A typical SHM systems comprises of sensor such as, strain gauges, newlineaccelerometers, piezoelectric sensors, and fibre optic sensors mounted or embedded in newlineconcrete structures for SHM applications. However, due to their poor compatibility with newlineconcrete and low sensitivity and survival rate, electrical sensors eventually separate and newlinecorrode. These sensors are expensive to install, have a short lifespan, and need a high level newlineof competence. To overcome drawbacks of conventional sensors, the present study newlineproposes to development smart multifunctional self-sensing cement-based sensor. The newlinerecent era of nano technology enables the development of smart self-sensing materials. newlineThese self-sensing materials possess piezoresistive properties which are able to detect newlinedamages, propagation of internal cracks with respect to change in stress, strain with respect newlineto load, temperature, environmental condition by correlating to the change in resistance. In this context, the present study involves the development of smart hybrid multi-functional cement based nano composite embedded sensor for SHM applications. newline
