“…En la investigación de [42] se realizó la evaluación de tres tamaños de 5/10, 5/14 y 5/19 mm de agregado grueso, con un contenido de escoria de acero de horno eléctrico en porcentajes de 0, 25, 50, 75 y 100 %; se evaluaron la tracción, absorción de agua, absorción superficial inicial, porosidad, permeabilidad y resistencia al ataque de sulfatos. Por otro lado, en [43] se realizó una mezcla comparativa a base de áridos naturales en tamaños de 0/4, 4/8 y 8/16 mm.…”

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.

“…This initiative contributes to developing inclusive, safe, resilient, and sustainable urban environments. Studies indicate that IFS' higher density and lower water absorption rate improve concrete properties, furthering sustainable construction methods [25]. Such an approach also advances SDG-12, which calls for responsible consumption and production by enhancing resource efficiency and reducing waste [26].…”

This research investigates the potential of utilizing recycled concrete aggregate (RCA) and recycled sand (RS), derived from crushed concrete cubes, as sustainable alternatives in construction materials. The study comprehensively evaluates the properties of RCA and RS, focusing on workability, impact resistance, abrasion resistance, and compressive strength to determine their viability as substitute construction materials. A notable finding is RS’s enhanced fire and heat resistance when used as a fine aggregate in mortar blends, mixed with cement and Sinicon PP in a 3:1 ratio. The experimental analysis included thorough assessments of uniformity, durability, and curing time, alongside Scanning Electron Microscopy (SEM) for structural examination. Results show that RCA has an Aggregate Impact Value (AIV) of 5.76% and a Los Angeles Abrasion Value (LAA) of 21.78%, demonstrating excellent strength of the recycled aggregates. The mortar mix was also prepared using recycled sand, cement, and Sinicon PP, and its stability was confirmed through soundness tests, which resulted in a 0.53 mm expansion and a satisfactory consistency level of 44%. Ultrasonic pulse velocity (UPV) tests also indicated high-quality concrete formation using RCA and RS. SEM imaging corroborated this by revealing a bond between the cement paste and the aggregates. Incorporating RS and RCA in concrete mixtures impressively yielded a compressive strength of 26.22 N/mm2 in M20-grade concrete. The study concludes that using RCA and RS waste materials in the construction sector underlines that sustainable practices can be integrated without compromising material quality. This approach aligns with sustainable development goals and fosters a more environmentally friendly construction industry.

“…Concrete, a globally fundamental construction material, represents a significant investment for national economies. Approximately 60-75% of this material consists of aggregate components, with around 10-15% comprising Portland cement or cementitious materials, along with water [1][2][3]. In the current era characterized by advanced technologies and finite natural resources, the production of concrete is expected to yield long life, contribute to environmental and public health, exhibit resilience to external influences, require minimal maintenance, and entail low costs [4].…”

Alkali–silica reaction (ASR) occurs when alkali oxides coming from the cement composition in concrete come together with reactive silica and moisture coming from the aggregate. Additional maintenance and repair costs caused by the development of ASR in concrete cause the cost to increase. However, thanks to the measures taken against ASR in the early period, it contributes to the creation of sustainable and durable concrete structures. The article investigated the usability of cherts with eight different chemical compositions as aggregates in ready-mixed concrete plants in Gümüşhane. Cherts have been investigated for alkaline reactivity and are intended to be used largely as a source for concrete plants. ASR length changes of the samples prepared according to ASTM C1260 standard were determined after 3, 7, 14, and 28 days of the curing period. Microstructural examination, ultrasonic P-wave velocity, and bending and compressive strength experiments supporting ASR were carried out. The obtained test results were compared between the reference (limestone) sample and each other, as well as with the values specified in the standards. The compressive and bending strength values of the samples increase depending on their ASR. It was observed that the crack structures and types increased depending on the increase in the crack values.
