“…These materials are based on the addition of electrically conductive fibres or particles to the cement matrix and the modification of its electrical properties, without compromising the mechanical performance of the composite material. In this context, Lataste et al [25] concluded that the variation of the electrical properties of cementitious materials reinforced with metallic fibres depends on the amount and morphology of the added fibres and also on their physico-mechanical properties, moisture content, and their distribution and connectivity inside the material.…”

Effect of Metallic Waste Addition on the Physical and Mechanical Properties of Cement-Based Mortars

Featured Application: The development of advance construction materials based on waste valorisation is a reality. The cement-based mortar with recycled metallic waste presented in this study could be potentially used as a building material with crack self-monitoring properties.Abstract: This paper investigates the influence of the type and amount of recycled metallic waste on the physical and mechanical properties of cement-based mortars. The physical and mechanical properties of cement mortars, containing four different amounts of metallic waste (ranged 4 to 16% by cement weight), were evaluated by measuring the bulk density, total porosity, flexural and compressive resistance, and dynamic elastic modulus by ultrasonic tests. All the properties were measured on test specimens under two curing ages: 7 and 28 days. Additionally, the morphological properties and elemental composition of the cement and metallic waste were evaluated by using Scanning Electron Microscopy (SEM), energy dispersive X-ray spectroscopy (EDXS), and X-ray fluorescence (XRF). Main results showed that the addition of metallic waste reduced the bulk density and increased the porosity of the cement-based mortars. Furthermore, it was observed that flexural and compressive strength proportionally increased with the metallic waste addition. Likewise, it was proven that elastic modulus, obtained by compressive and ultrasonic tests, increases with the metallic waste amount. Finally, based on a probability analysis, it was confirmed that the addition of metallic waste did not present a significant effect on the mechanical performance of the cement-based mortars.

“…The fiber distribution may be evaluated through video recording during casting. However, this information is limited to the mass surface (Lataste et al, 2008). Image analysis has been used to determine the distribution inside the concrete mass (Akkaya et al, 2000;Chermant et al, 2001;Lawler et al, 2003).…”

“…Measuring the electrical resistivity was also found to be able to help to determine the fiber distribution (Lataste et al, 2008). Such electromagnetic methods can be used either for laboratory specimens or small elements (Torrents et al, 2012) or for real size structures The fiber distribution in precast elements, in an industrial setting, was studied using drilled cores from the FRC, with the fiber orientation determined using X-ray analysis and the fiber content determined by crushing the cores.…”

“…To determine the actual reinforcement available in each direction of the concrete volume, due to the relevance of the distribution and orientation of the fibers in the development of suitable and reliable material properties for structural design, many researchers have studied the distribution of fibers theoretically and/or at the laboratory level, for example, Akkaya et al (2000), Chermant et al (2001), Chung (2001), Lawler et al (2003, Dupont and Vandewalle (2005), Ozyurt (2007), Lataste et al (2008), Lee and Kim (2010), and the comprehensive RILEM TC 162 (2003), among others.…”

This paper presents research results regarding the distribution of steel fibers in concrete used to build precast tunnel segments for Line 9 of the Barcelona Metro. The fiber distribution was studied using the actual fiber contents obtained by means of crushed cores drilled from different points of three full-scale tunnel lining segments. A statistical analysis determined that the fiber content in the ends of segments tend to be greater than in the central zone. In addition, cores with a diameter of 150 mm were found to have a lower scatter in the fiber content than smaller diameter specimens. Finally, based on probabilistic approaches, a minimum of 11 cores is proposed to control the fiber content in FRC segments.
