“…87 Even though it is easy to disperse NCB in aqueous solution, large quantity (<1%) of NCB is required to create a conductive network inside the cement composite. 7 However, dispersion of NCB content >1.5% leads to agglomeration, resulting in embrittlement 85 and attenuation of the compressive strength of the cement composites. 87 Figure 7 shows the level of reduction in compressive strength as a function of NCB content from different studies.…”

“…89 It is claimed that addition of a fibrous material (SF/CF/PPF/polymer) to NCB as a diphasic conductive material improves the compressive strength, flexural strength, post cracking and self-sensing behavior, and also produces a lower noise to signal ratio because of the synergistic effect. 40,85,[90][91][92] Electrostatic self-assembled nano carbon materials added along with NCB gives ameliorated contribution in high performance in terms of repeatability, electrical conductivity, mechanical, and piezoresistive properties. 54,[93][94][95][96] Sensors developed with CNB/Ni-NF improves the correlative effect resulting in good humidity, adaptability and acquires better temperature sensitivity for SHM.…”

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.

The use of recycled reinforcements in structural applications is growing due to concerns about the environmental impact and economic costs associated with energy‐intensive production techniques of virgin fibers. However, limited research has explored the integration of multiscale reinforcements with different aspect ratios into PA66 composites to enhance their performance. In this study, the effect of reinforcement aspect ratio on PA66 composites by incorporating recycled carbon fibers and waste tire‐derived graphene nanoplatelets (GNP) with oxygen surface functional groups is investigated. The objective of this work is to improve mechanical properties of the composites by promoting nucleation and enhancing the fiber/matrix interface. Through high shear mixing, recycled carbon fibers and GNP are effectively dispersed within the PA66 matrix. The alignment of these reinforcements during the injection molding process is monitored using the developed flow model, coupled with experimental rheological data. The resulting composites demonstrate significant improvements in mechanical properties due to enhanced interfacial interactions, including improved tensile properties up to 94%, flexural properties up to 86% compared to the neat PA66 by successfully integrating waste tire‐driven GNP and recycled carbon fibers. This study contributes to the development of sustainable materials for load‐bearing applications, utilizing recycled reinforcements with different aspect ratios.
