“…Fig. 1 shows the representation of the procedure of hydrolyse of the TEOS, based on [24,33,34]. Since TEOS is not miscible in water, a 1:1 solution by volume of ethanol (C2H6O with purity higher than 96%) in water was used to disperse the silane.…”

“…Studies with silane coupling agents showed the possibility of producing sheets of hybrid calcium silicate hydrate from the reaction of hydrolysed silanes in calcium hydroxide solution at room temperature [20][21][22]. Other studies revealed the potential use of silanes to improve properties in cement-based materials, such as workability or durability [23][24][25][26][27][28].…”

This paper explores the effect of fibre functionalization with tetraethoxysilane (TEOS) in the microstructure and mechanical property of ultra-high performance cement composites with steel fibres. Fibres treated with three concentrations of TEOS were evaluated by pullout tests and SEM/EDS analysis. Mixes with treated fibres showed up to 35.6% increase in bond strength and up to 49.5% reduction in the crack opening at the peak pullout load in comparison with

“…pitch-based or polyacrylonitrile-based) [22,32] , and the surface chemistry of carbon fiber strands [32,33] influence the effectiveness of fibers in modifying the properties of concrete. Percolation of fibers in concrete depends on dispersion level, that is, controlled by fiber properties, mixture constituents, mix proportions, and mixing procedure [21,28,34,35]. Improved fiber dispersion leads to improved fiber-cement paste bond, higher ductility, and reduced electrical resistivity [33].…”

This research was inspired by the need to optimize the mix design of electrically conductive concrete (ECON) for field implementation. Carbon fiber was used for producing ECON with different mixing proportions and constituents. Calcium nitrite-based corrosion inhibitor admixture and methylcellulose were used as conductivity-enhancing agent (CEA) and fiber-dispersive agent (FDA) respectively. Five easy-to-change mix design variables were evaluated for their effects on electrical conductivity and strength of ECON: carbon fiber dosage, fiber length, coarse-to-fine aggregate volume ratio (C/F), CEA dosage, and FDA dosage. The results approved the effectiveness of the applied CEA in improving electrical conductivity while positively influencing strength. Conductivity was significantly influenced by: fiber content, C/F, fiber length, and CEA dosage. The dosages of Fiber, CEA, and FDA exerted significant influence on compressive strength. C/F and FDA dosage were significant variables influencing flexural strength.

“…Moreover due to the weak strength between the carbon fibre and cement matrix, the introduction of latex, silica fume or methylcellulose can improve the bond between the fibre and matrix, thereby improving the mechanical properties of the cement composites [22,23]. A surface pretreatment of carbon fibre or treating silica fume with silane can improve the bond strength between carbon fibre and the cement matrix and the dispersion degree of conductive fillers, thereby increase the shielding effectiveness of the composites [24][25][26].…”
