To create a simple way to keep an eye on the health of concrete structures. Small amounts of short (5mm length) carbon fibres added to mortar or concrete (0.2 to 0.5% by volume of cement) have been shown to induce self-sensing or intelligent behaviour. Due of this, electrical resistance increased under loading, resulting in crack propagation or fracture. The resistance change cannot be reversed once it reaches the inelastic stage for the purpose of monitoring the health of structures, an approach that can be utilised in place of fibre optic or strain gauge technology has been devised. When fibres are pulled out in the elastic range, resistance rises. A four-probe approach was used to measure the change in elastic resistance, and it was discovered that elastic deformation might reverse the change. Additionally, the specimen's irreversible resistance change can be used to detect the spread of cracks and fibre breakage. The graphs of load versus resistance were drawn. This phenomenon can be used to determine the weight of moving vehicles in real time as well as the stress levels within a loaded building, among other things.
