“…The addition of waste carpet fibers at a volume fraction of 1.0% slowed down the compressive strength development of coarse ceramic aggregate concrete, while steel fibers at a volume fraction of up to 1.5% led to an increase in the compressive strength development of coarse ceramic aggregate concrete [27,89]. To study the impact of steel chips and coarse porcelain tile aggregates on the compressive strength of concrete, Keshavarz et al [90] developed a threedimensional model of the compressive strength of concrete, as shown in Fig. 11.…”

“…Steel fibers could improve the tensile strength of concrete, and the splitting tensile strength of ceramic aggregate concrete usually increased with steel fiber content (volume fraction no more than 1.5%) [89,99]. Keshavarz et al [90] investigated the impact of both coarse ceramic aggregates and steel chip content on the tensile strength of concrete, and found that the tensile properties of concrete containing 50% coarse ceramic aggregates and 1% steel chips performed the best in their study. Moreover, the bridging effect of carpet fibers was responsible for the significant improvement in the tensile properties of concrete containing carpet fibers and ceramic aggregates [27].…”

Green and sustainable concrete has attracted significant attention from the construction industry and researchers since it was proposed. The ceramic waste materials are often directly buried in the ground or placed in an open dump, and the accumulation of ceramic waste contributes to environmental pollution, which makes the recycling of ceramic waste quite urgent. Owing to the pozzolanic activity, excellent mechanical properties and durability, industrial ceramic waste is considered as a suitable substitute for cement or natural aggregates to fabricate renewable concrete. In this paper, the pozzolanic activity of ceramic waste and the workability, mechanical performance, and durability of ceramic concrete are discussed. In addition, the most recent research results pertaining to ceramic concrete are reviewed. Ground ceramic powder improves the workability, compressive strength, resistance to chloride penetration, and carbonation resistance of concrete to a certain extent. Concrete containing ceramic as the aggregate has a lower mechanical performance than ordinary concrete. However, the resistance to chloride penetration, freeze-thaw resistance, and high-temperature resistance of ceramic concrete are remarkable. Ceramic concrete is environmentally friendly, requires fewer energy resources to manufacture than ordinary concrete, and has excellent engineering properties. However, further research is required for future engineering applications.

“…Recycled coarse aggregate is commonly used as a replacement for standard aggregate in concrete mixtures [14][15][16], and is also widely used to strengthen road substrates [17,18]. In literature, there are well-known approaches of using marble [19][20][21], granite [22][23][24], ceramic [25,26], electric arc furnace slag [27], and steel slag [28,29] as recycled coarse aggregate. Gao et al [30] performed tests on recycled aggregate concrete strengthened with polyester FRP-PVC (fiber reinforced polymer-polyvinyl chloride) tubes.…”

Nowadays, the recycled fine aggregate sourced from construction and demolition waste is not frequently used in manufacturing of epoxy resin coatings. Therefore, the main novelty of the article is to prepare green epoxy resin coatings modified with recycled fine aggregate in a replacement ratio of natural fine aggregate ranged from 20 to 100%. The microstructural properties of the aggregates and epoxy resin were analyzed using micro-computed tomography, scanning electron microscopy and nanoindentation. The macroscopic mechanical properties were examined using pull-off strength tests. The highest improvement of the mechanical properties was observed for epoxy resin coatings modified with 20% of natural fine aggregate and 80% of recycled fine aggregate. It has been found that even 100% of natural fine aggregate can be successfully replaced using the recycled fine aggregate with consequent improvement of the pull-off strength of analyzed epoxy resin coatings. In order to confirm the assumptions resulting from the conducted research, an original analytical and numerical failure model proved the superior behavior of modified coating was developed.

“…Claramente, esta situación es peligrosa para el medio ambiente y conduce a la erosión del suelo, contaminación del aire, paisajes devastados y hábitats pobres para la vida silvestre. La mejor manera de manejar los desechos parece involucrar su separación en la fuente y su reciclaje para la reutilización en la producción [7].…”

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.
