“…Song et al [ 19 ] also performed the structural health monitoring of a specially designed concrete bent-cap, indicating that the smart aggregate is able to capture the moment of concrete cracking. More recently, smart aggregates have been increasing employed in the monitoring field, involving the strength monitoring of early age concrete [ 20 ], impact detection and evaluation [ 21 ], health monitoring [ 22 , 23 , 24 , 25 , 26 , 27 ] and damage detection [ 28 , 29 ].…”

In order to explore the crack development mechanism and damage self-repairing capacity of ECC beams reinforced with hybrid bars, the smart aggregate-based active sensing approach were herein adopted to conduct damage monitoring of ECC beams under cyclic loading. A total of six beams, including five engineered cementitious composite (ECC) beams reinforced with different bars and one reinforcement concrete counterpart, were fabricated and tested under cyclic loading. The ultimate failure modes and hysteresis curves were obtained and discussed herein, demonstrating the multiple crack behavior and excellent ductility of ECC material. The damage of the tested beams was monitored by smart aggregate-based (SA) active sensing method, in which two SAs pasted on both beam ends were used as actuator and sensor, respectively. The time domain analysis, wavelet packet-based energy analysis and wavelet packet-based damage index analysis were performed to quantitatively evaluate the crack development. To evaluate the self-repairing capacity of the beams, a self-repairing index defined by the difference of damage index at loading and unloading peak points was proposed. The results in time domain and wavelet packed analysis were in close agreement with the observed crack development, revealing the feasibility of smart aggregate-based active sensing approach in damage detection for ECC beams. Especially, the proposed damage self-repairing index can describe the same structural re-centering phenomena with the test results, showing the proposed index can be used to evaluate the damage self-repairing capacity.

Keywords Infrastructure proliferation Concrete utilization Structural health monitoring (SHM) Smart aggregates Developmental directionsIn recent times, the use of concrete has greatly increased alongside the rapid growth of global infrastructure. However, concrete structures face various risks like dynamic forces from winds or earthquakes and environmental impacts like corrosion. These challenges are more significant due to the saturation of infrastructure projects worldwide. To tackle these issues and ensure the long-term strength of structures, the field of structural health monitoring (SHM) has become incredibly important. One promising technology in this area is the use of smart aggregates. These are special materials that are embedded in concrete and serve three main purposes: monitoring early concrete strength, detecting impacts, and continuously monitoring the health of structures. Smart aggregates have several advantages, including being able to detect a wide range of frequencies, responding quickly, being easy to make, process, and cost-effective. Because of these benefits, they are becoming widely used for monitoring the health of structures. As time has passed, there have been significant improvements in smart aggregate technology. This article provides a comprehensive overview of the basic principles behind using smart aggregates for structural health monitoring. It also discusses the progress made in the last twenty years in three main areas: technology development, measurement range, and wireless capabilities. Additionally, the article briefly discusses recent real-world uses of smart aggregates for structural health monitoring. Looking ahead, the article outlines potential future trends in the development of smart aggregate technology. It emphasizes the need for more research to better understand how these materials perform and how effective they are in different situations. This research is crucial for making further advancements in ensuring the durability and safety of structures.
