“…Similar to our findings, studies have demonstrated that adding RHA 95 , 105 – 107 , NS 41 , 108 – 110 , and NA 103 , 111 to concrete reduces chloride ion penetration and water absorption. Furthermore, adding nano to RHA-enriched cement mortars improved the composite’s chloride resistance 112 , while adding polyethylene terephthalate aggregates increases the depth of water penetration 113 . Moreover, adding of fly ash and coal gangue decreased the chloride diffusion coefficient 114 .…”

Various studies have been recently conducted aiming at developing more sustainable cementitious systems so that concrete structures may not have a negative effect on the environment and are decomposed. It has been attempted to build sustainable binders by substituting silica fume, cement with fly ash, nano-silica, nano-alumina, and rice husk ash. In this paper, a series of experiments on concrete with different contents of rice husk ash (10%, 15%, and 20%), nano$${{\hbox {SiO}_2}}$$ SiO 2 (1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%), and nano$$\hbox {Al}_{2}{\hbox {O}}_{3}$$ Al 2 O 3 (1%, 2%, 3%, 4%) are performed to analyze the durability and mechanical properties of samples under the curing condition of Caspian seawater. The workability, density, water penetration, chloride ion penetration, and compressive strength (at 7, 14, 28, and 90 day) of the samples were determined. The experimental results showed that workability decreased gradually with increasing additives content, while the compressive gradually increased. Among the additives, adding 8% of the nano$${{\hbox {SiO}_2}}$$ SiO 2 had the most significant effect on the improvement of compressive strength. Adding 8% nano$${{\hbox {SiO}_2}}$$ SiO 2 and 4% nano$$\hbox {Al}_{2}{\hbox {O}}_{3}$$ Al 2 O 3 reduced the depth of water permeability by 53% and 30%, respectively. Furthermore, adding 8% nano$${{\hbox {SiO}_2}}$$ SiO 2 reduced chloride ion penetration by 85%.

“…The studies done by previous studies at 20% replacement of natural river sand with PET waste revealed a 75%, 5%, and 28% reduction in compressive strength [102][103][104]. However, the variation in strength was seen in different studies, and trends show precise observation of declining strength at a higher replacement ratio of up to 20%.…”

Addressing the environmental threat of Polyethylene Terephthalate (PET) waste is critical for sustainable development. Despite PET's prevalence in everyday products, its improper disposal endangers environmental health. This study targets a pivotal gap in current research. PET waste's potential as a sustainable building material will be thoroughly evaluated, focusing on whether recycling PET waste is feasible. In the construction industry, it can be a substitute for natural sand and an additive in cement. This study contributes to a dual-purpose solution: mitigating environmental pollution and innovating in construction material science. The systematic literature review (SLR) delves into existing studies, focusing on PET's impact on concrete properties when substituting natural sand at ratios of 5% to 20% and as a cement additive at 0.5% to 2% by weight. The findings revealed that up to a 10% PET replacement enhances compressive strength, highlighting a sustainable pathway for construction practices. However, replacements above 10% show a reduction in strength, indicating an optimal substitution threshold. Moreover, incorporating PET additives at 1% by cement weight optimizes flexural strength, underscoring the material's viability in enhancing structural integrity. This study sheds light on PET waste's application in reducing environmental impact and proposes a viable, eco-friendly alternative for construction materials. The recommendation for further research underscores the necessity to refine PET's application in construction, aiming to bridge the knowledge gap and encourage sustainable future innovations.

“…Saxena et al [31] observaron que la profundidad de penetración del agua para una relación de 0:45 a/c sin residuos de PET después de 28 días de curado era de 24 mm y aumentaba con el incremento de residuos PET en el concreto. También observaron que eran de 24 mm, 28 mm, 42 mm, 71 mm y 105 mm en remplazos del 0 %, 5 %, 10 %, 15 % y 20 % de agregado.…”

El impacto socioambiental que provoca la generación impulsiva de residuos orgánicos e inorgánicos sin destino final adecuado es alarmante en la actualidad. Por lo anterior, se propone un uso más técnico de las fibras polietileno tereftalato (PET) en la construcción. Este artículo tuvo como objetivos revisar la literatura de 50 artículos científicos de diversas revistas y analizar los diferentes efectos en las propiedades del concreto por la incorporación de agregados PET. La metodología corresponde a la búsqueda, selección y análisis de diferentes estudios. La revisión permitió observar mejores resultados con respecto al rendimiento de flexión posterior al agrietamiento y su ductilidad que mejoran debido al uso de fibra de PET. Por otra parte, los valores de resistencia a compresión axial y a tracción por compresión diametral del compuesto se ven disminuidos cuando se incorpora mayor porcentaje de fibras PET. Estas últimas llegan a ser un gran aliado en la reducción de fisuras, la deflexión de elementos estructurales, la resistencia a la abrasión del concreto; aumentó con el incremento de residuos de PET como remplazo, de agregado grueso; en el ensayo de resistencia al desgaste por abrasión disminuyó en 0,42 mm a 0,23 mm. Así, se demuestra que las fibras PET constituyen una alternativa sostenible como agregado que dan beneficios en las diferentes propiedades del concreto, pero no se debe incorporar una cantidad mayor al 5 % del volumen total, ya que no existiría ningún beneficio a la mezcla endurecida.
