“…In general, the addition of WRPF resulted in the decreased CS of CBCs [32,41,42,71,113]. The loss of CS was documented in several studies carried out to investigate the MPs of CBCs comprising PET waste fibers of varying content and length [69,[114][115][116].…”

Ecological problems such as natural resource depletion and massive quantities of waste for disposal are now guiding progressive civilization towards sustainable construction. The reduction of natural resources and the discarding of debris into open landfills are the two main environmental concerns. As a result, managing these solid wastes is a major challenge worldwide. In comparison to disposal, insufficient landfills, ecological degradation and the economic load on the relevant agencies, recycling and reusing waste materials have a considerable influence. Waste fiber has been studied for use as a cement-based composite (CBC) ingredient. Recycling waste fibers not only makes the cement composite more cost-effective and long-lasting but also helps to reduce pollution. Plastics, carpets and steels are among the various types of waste fibers reviewed in this study for their applications in cement-based materials. The mechanical properties of CBCs with different kinds of recycled-waste fibers were explored, including their compressive, flexural and splitting tensile strength and durability properties. The use of recycled fibers in the construction industry can help to ensure sustainability from environmental, economic and social standpoints. As a result, additional scientific research is needed, as well as guidance for more researchers and experts in the construction sector to examine the unknown sustainability paths. The barriers to the effective implementation of waste fiber recycling techniques in the construction sector were reviewed, and various solutions were proposed to stimulate and ensure their use in CBCs. It was concluded that CBCs containing recycled fibers provide a long-term and cost-effective alternative for dealing with waste materials.

En la actualidad, el interés por usar materiales de desecho y subproductos provenientes del hormigón ha incrementado, debido a la necesidad de minimizar la contaminación en el planeta. El presente documento tiene como objetivo la revisión sistemática de la literatura con respecto a la implementación de los residuos de acero en la mezcla de hormigón, y cómo esto influye en su comportamiento físico-mecánico. Se ha enfocado el interés principalmente en los residuos de acero en forma de escoria, limadura, viruta y fibras, incorporados en todo tipo de hormigón estructural, utilizado en columnas, vigas, zapatas, losas y muros. El uso de estos materiales tiene un alto impacto, pues no solo ayuda a reducir el costo de fabricación de cemento y hormigón, sino que a la vez otorga numerosos beneficios ecológicos, como reducir el costo de los vertederos, ahorrar energía y proteger el medio ambiente de una posible contaminación. Se efectuó la búsqueda de artículos indexados en las diversas bases de datos, tales como ASCE, EBSCO, Google Scholar, ScienceDirect, Scopus y SpringerOpen; se seleccionó finalmente un total de 60 artículos publicados desde el año 2014. Se concluye que el uso de residuos de acero es una alternativa para incorporar a la mezcla de hormigón, pues puede reemplazar parcial o totalmente al agregado y lograr la producción de hormigones que no presenten afección en sus propiedades físico-mecánicas; e incluso, en algunos casos, mejorar dichas características.

“…Experimental studies have been conducted to replace the reinforcements of reinforced concrete with bers capable of providing good tensile, exural, and shear strength to concrete [13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Initially, researchers attempted to increase the mechanical characteristics of concrete such as compressive strength and exural strength by adding bers, but the result obtained was limited [27].…”

This work focuses on the experimental study of mechanical behavior through "3-point bending" tests on concrete slabs reinforced with two types of fibers: metallic fibers (MF) and grids based on polypropylene fibers (PPF). The metallic fibers are sourced from machining waste of steel parts, randomly dispersed within the concrete, while the grids consist of polypropylene fibers. Bending tests are conducted on slabs with dimensions [25x50x7] cm³. Compression tests are also carried out on cylinders with a diameter of Ø160 mm and a height of H320 mm. The fibers are characterized in terms of mechanical strength and pull-out resistance. The concrete composition is determined using the experimental method known as the "Dreux-Gorisse" method. For this study, five contents of metallic fibers (MF) are selected (W = 0.2%, W = 0.4%, W = 0.6%, W = 0.8%, and W = 1%). A control concrete (BT) with a fiber content of 0% (W = 0%) is prepared to serve as a reference. Two variants of polypropylene fibers, small mesh (PPF/SM) and large mesh (PPF/LM), are also included. By comparing and contrasting the results obtained with those of Mohsin Adeel Waris et al [37], it is evident that adding metallic fibers (MF) to concrete at a fiber percentage (W = 0.8%) enhances both strength and stiffness better than adding polypropylene grid fibers, as well as better than the combination of steel and rubber fibers for volumes (Vf = 0.1(SF) + 2% (RF)) [37]. The metallic fibers used restrain cracking due to tilting.
