“…An SCC must possess high electromechanical properties to monitor the structural components successfully. Te performance index (PI) technique, a management tool that integrates several data sets, is utilized to optimize SCC [13,58]. If the primary requirement for a cement composite is strength, PI 1 should be used.…”

“…Due to its excellent compatibility and durability, SCC constructed of conductive materials plays a vital part in the SHM compared to traditional sensors. Steel fber (SF), carbon nanotube (CNT), carbon black (CB), carbon fber (CF), nickel powder (NP), and graphite powder (GP) are conductive materials that can help develop the SCC [11][12][13][14][15][16]. Both fber and powder materials can develop SCC to detect stress, strain, and damage in concrete structures under monotonic and cyclic loads [17].…”

This research examines the electromechanical characteristics of self-sensing cement composite (SCC) containing activated charcoal (AC) at various concentrations (5%, 10%, 15%, 20%, and 25%). The developed composite is placed in various zones in the beam to monitor beam behaviour, as well as in the column center to monitor column deflection. The research reveals that AC reduced the compressive strength and resistivity of cement composites by generating local hydration and carbon accumulation. The performance index approach optimizes AC concentrations at 25% and 20% without and with 10% silica fume (SF), respectively. The embedded SCC has monitored the deflection of beams and columns with a maximum correlation between electrical resistivity and deflection at 99% and 96%, respectively. According to the findings, the AC can generate SCC, which might be utilized to monitor the deflection of beams and columns.

The integration of self‐sensing ability and different functional properties of nanomaterials into construction materials leads to smart and multifunctional cementitious sensor composites. Significant evolution of the Structural Health Monitoring (SHM) has helped to elevate the life span and mitigate damages of the structure. Developing smart cementitious sensor composite with electrical properties as a parent element and embedding it in the structural components have proved to be advantageous in terms of evaluating the damages, monitoring the periodic health and life assessment of the structures. In this review, the copious development processes and various methods of designing smart‐sensing cementitious composites have been scrutinized. This work recapitulates the principle of self‐sensing technique, typical functional fillers, trends of percolation threshold, dispersing material, dispersion technology, and also describes the required sensing ability of the sensors using the conduction theory. Subsequently application of smart cement‐sensors in structural components for SHM is discussed. In addition, this review article provides comprehensive information on the effects of nano materials and their dispersion in the development for smart and multifaceted cementitious sensor composites with enhanced sensitivity parameters and economic benefits that are suitable for future prospects.

Fully embedded and spatially diffuse sensors are central to the advancement of civil and construction engineering. Indeed, they serve as an enabling technology necessary for addressing the current challenges associated with through‐life management and structural health monitoring of existing structures and infrastructures. The need to identify structural issues early on has driven the integration of such embedded sensing capabilities into construction materials, turning passive structures into proactive, self‐aware “entities,” commonly referred to as Smart Structures. The economic rationale behind this endeavor is underscored by the vital significance of continuous monitoring, which enables prompt anomaly assessment and thus mitigates the risks of potential structural failures. This is particularly relevant for road and rail infrastructures, as they represent a substantial and enduring investment for any nation. Given that a large majority of these large infrastructures are composed of concrete and reinforced concrete, both academics and construction companies are continuously researching micro‐ and nano‐engineered self‐sensing solutions specifically tailored for this building material. This comprehensive review paper reports the latest advances in the field of self‐sensing concrete as of 2024, with an emphasis on intrinsic self‐sensing concrete, that is, electrically conductive functional fillers. A critical analysis and a discussion of the findings are provided. Based on the perceived existing gaps and demands from the industry, the field's future perspectives are also briefly outlined.
