“…They represent one third of the total waste volume generated by industrial activities, which in the EU-28 is about 3 billion tons per year [1]. CDWs derive from construction and demolition activities and mainly contain concrete, masonry, asphalt and metals [2]. It is estimated that approximately 54% of CDW is comprised of ceramic materials (i.e., bricks and tiles), while approximately 12% is concrete [3].…”

“…On the other hand, the energy requirements for the production of concrete are almost 5% of the global energy consumption. Moreover, the production of 1 ton of cement results in emissions of approximately 1 ton of carbon dioxide (CO 2 ), while aggregate production also poses severe problems to surrounding areas [2,5,6].…”

“…The alkaline solutions, mainly sodium or potassium hydroxide and silicate solutions, act as activators to initiate polymerization of Si and Al present in the raw materials and for the formation of Si-O-Al-O bonds [12]. Raw materials rich in silica and alumina, including bricks, ceramic waste, metakaolin, fly ash, kaolin and slag can be used for the production of IPs [2,12]. Apart from the construction sector, the produced IPs may be used for the immobilization of hazardous elements or as adsorbents in various industrial processes [13][14][15][16][17].…”

This paper explores the alkali activation potential of brick wastes and metallurgical slags. Inorganic polymers (IPs) were produced using an alkaline medium consisting of sodium hydroxide and sodium silicate solutions and the optimum synthesis conditions were determined. In this context, the variable parameters, such as solid to liquid (S/L) ratio, curing temperature (60, 80 and 90 °C) and ageing time (7 and 28 days) on the compressive strength and the morphology of the produced IPs were investigated. Specimens produced under the optimum synthesis conditions were subjected to high temperature firing and immersed in distilled water and acidic solutions for various periods of time, in order to assess their durability and structural integrity. The results showed that the IPs produced using a mix ratio of 50 wt % metallurgical slag and 50 wt % brick wastes, cured at 90 °C and aged for 7 days obtained the highest compressive strength (48.9 MPa). X-ray fluorescence analysis (XRF), particle size analysis, Fourier transform infrared spectroscopy (FTIR), mineralogical analysis (XRD), mercury intrusion porosimetry (MIP), scanning electron microscopy (SEM) and thermogravimetric (TG) analysis also confirmed the optimum microstructural characteristics and the chemical reactions that took place during synthesis. The overall results of this study indicate that the co-valorization of different waste streams, which are produced in large quantities and cause environmental problems if not properly managed, is a viable alternative for the production of binders or secondary construction materials with higher added value.

“…El uso del residuo de mampostería (RM) como reemplazo parcial del cemento Portland disminuye el impacto negativo y los costos en la elaboración de concreto autocompactante (CAC). Sin embargo estudios sobre la durabilidad de CAC con RM no han sido reali-civiles (Wong et al 2018;Muduli y Mukharjee, 2019), los cuales son depositados en vertederos y como relleno en canteras donde ya no se extrae material, lo cual conduce a un aumento de costo por el transporte y eliminación (Bravo et al 2015).…”

“…Los RCD consisten en su mayoría en residuos sólidos de tipo inertes como concreto, mortero, ladrillo, metal, cerámica, madera, plástico y vidrio, los cuales pueden ser reciclados (Islam et al 2019). Los ladrillos o residuos de mamposteria son el segundo material más empleado en la construcción después del concreto (Wong et al 2018;Gálvez-Martos et al 2018), el cual hace parte de los RCD. Además, este residuo se genera también durante su fabricación (Ercikdi et al 2015).…”

En este trabajo se presentan resultados de un estudio experimental sobre la resistencia al ataque externo de sulfato de sodio (Na2SO4) en concretos autocompactantes (CACs) con residuo de mampostería (RM). Los CACs presentaban un contenido de agua constante de 202,5 kg/m3 y diferentes volúmenes de RM (0%, 25% Y 50%) como reemplazo parcial de cemento Portland (OPC) expuesto a una solución de sulfato de sodio al 5%. Las propiedades en estado fresco como fluidez, capacidad de paso y resistencia a la segregación se evaluaron mediante el flujo de asentamiento, embudo en V y caja en L. En estado endurecido, la resistencia a la compresión y expansión fueron determinadas. Por otra parte, técnicas de difracción de rayos X (DRX), microscopia electrónica de barrido (MEB) y espectroscopia de Infrarrojo con transformada de Fourier (FTIR) fueron aplicadas en pastas para investigar los efectos de los sulfatos sobre la microestructura. Los resultados mostraron que todas las mezclas cumplen las propiedades en estado fresco, además se encontró que cuando los CACs son inmersos en la solución de sulfato de sodio, el RM puede mejorar la resistencia de los CACs al ataque por sulfatos en comparación con el CAC solo de OPC.

This study presents a cost‐effective and eco‐friendly method to produce aluminosilicate materials using red brick waste (RBW) and metakaolin (MK) as silica and alumina precursors. RBW was subjected to alkaline fusion to increase its dissolution for geopolymerization reaction. Response surface methodology was used to investigate the effect of NaOH concentration and fusion temperature on the leaching of silica and alumina from RBW. The microstructure of the alkali‐fused RBW was analyzed using x‐ray diffraction and Fourier‐transform infrared spectroscopy. Response surface methodology confirmed and revealed that higher NaOH concentration (14 M) and a temperature of 660°C favored solubilized phase development, resulting in 85% and 50% leached silica and alumina, respectively. These optimized parameters were then employed to prepare geopolymer materials with different proportions of alkali‐fused RBW and MK, using NaOH and Na2SiO3 as the alkaline solution. The elaborated geopolymer binders were characterized using various techniques such as x‐ray diffraction (DRX), Fourier‐transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermal conductivity (λ), and fire resistance. The results showed that geopolymers containing 30 wt.% of alkali‐fused RBW exerted good mechanical and thermal insulation properties compared to conventional cement materials. However, excessive RBW addition causes negative effects. In addition, it was found that the blended geopolymers exhibited an increase in heat release rate (HRR), resulting in reduced fire resistance due to the presence of unreacted NaOH. Overall, these findings confirmed the potential sustainable use of RBW to partially replace MK in geopolymer as a material for building construction.
