Strain sensors can be embedded in civil engineering infrastructures to perform real-time service life monitoring. Here, the sensing capability of piezoresistive cement-based composites loaded with carbon black (CB) particles is investigated. Several composite mixtures, with a CB filler loading up to 10% of binder mass, were mechanically tested under cyclic uniaxial compression, registering variations in electrical resistance as a function of deformation. The results show a reversible piezoresistive behaviour and a quasi-linear relation between the fractional change in resistivity and the compressive strain, in particular for those compositions with higher amount of CB. Gage factors of 30 and 24 were found for compositions containing 7 and 10% of binder mass, respectively. These findings suggest that the CB-cement composites may be a promising active material to monitor compressive strain in civil infrastructures such as concrete bridges and roadways.

“…into or onto the concrete structures [4][5][6][7][8]. However, these sensors have some drawbacks including low sensitivity, high cost, short lifespan and poor antiinterference performance, which make it difficult to utilize monitoring technology to a large scale in the realistic projects [9,10].…”

“…In the 1960s, the glass fiber reinforced plastic rebars became initially and extensively applied as a reinforcing material for concrete structures among many engineering societies worldwide. [ 1 ] With the inexorable development of industry and urgent demand of high performance materials, the fiber‐reinforced technologies began to be widely used into fiber‐reinforced cement‐matrix composites, [ 2 ] fiber‐reinforced metal‐matrix composites, [ 3 ] fiber‐reinforced ceramic‐matrix composites, [ 4 ] especially advanced polymer materials such as fiber‐reinforced polymer composites in recent decades. [ 5 ] Due to small specific gravity, high specific strength, and specific modulus of fiber‐reinforced polymer composites (FRPs) including glass, aramid, and carbon, they have attracted much attention and widely used in automobiles, the aerospace industry, sporting goods, and so on, resulting in to replacing metal counterparts.…”

Co‐deposition of catechol and polyethyleneimine onto polyethylene phthalate (PET) fiber by mussel‐inspiration is conducted and subsequently utilized to prepare polyethyleneimine/catechol modified PET fiber reinforced composites (polyethyleneimine (PEI)/CCh‐m‐PET FRCs). The surface polarity is characterized through the dynamic contact angle. The mechanical performances including tensile, flexural, and short beam shear strength are evaluated. Additionally, the single‐bundle pull‐out tests are carried out with the double‐end method. The analysis reveals that compared to the untreated PET reinforced composite, there are 33.49% and 34.35% increase of the critical load and peak load for PEI‐modified specimens, respectively, meanwhile the critical debonding energy and pull‐out energy calculated increase by 28.46% and 24.47%, respectively. The interlaminar shear strength and interfacial shear strength of modified PET can reach the values of 145.89 and 20.88 MPa, which are significantly improved by 58.01% and 70.94%.
