“…Entonces, con grava natural de 1/4" a 3/8", cemento Portland y látex de caucho de estireno butadieno (SBR), se produjo concreto permeable con dosificación de cemento-agregado (1: 4.5) con 0 % de polímeros, utilizando 400 kg de cemento por metro cubico de concreto, 1800 kg agregado grueso por metro cubico de concreto, con relación A/C entre 0.30 y 0.35, también dos porcentajes de SBR de 5 % y 8 % por peso de cemento [48]. Asimismo, se incorporó fibra de carbono curado parcialmente al concreto permeable, utilizado como agregado grueso en diferentes proporciones de 4.15 kg/m 3 y 5.9 kg/m 3 de concreto, pero en porcentaje representa, tanto 0.27 de volumen, como 0.4 volumen [49].…”

El objetivo de la presente revisión fue recopilar y discutir literatura científica sobre metodologías empleadas para la producción y elaboración del concreto innovador “concreto permeable”, como alternativa de diseño en pavimentos, con el remplazo parcial de agregado grueso por agregados reciclados, como látex de caucho al 5 % y 8 % por peso de cemento, ceniza volante entre el 0 % y el 70 % por volumen del cemento, y fibra de carbono al 0.27 % y 0.4 % por peso de agregado grueso. Esta revisión de literatura implicó seleccionar las publicaciones más relevantes, para los períodos del 2015 al 2021 en bases de datos indexadas Scopus, Scielo, ScienceDirect, y Latindex; enfocándose en múltiples parámetros como: “materiales residuales, coeficiente de permeabilidad, concreto permeable, grado de porosidad y ensayos de laboratorio para el concreto permeable”. Los resultados muestran que la resistencia a la compresión varía entre 0.5 MPa y 97.3 MPa, resistencia a la tracción entre 1.6 MPa y 5.29 MPa y la permeabilidad entre 4.63 mm/s y 10.2 mm/s, donde el porcentaje idóneo del uso de ceniza volante para la obtención óptima de concreto permeable es hasta el 20 %, que, excediendo este porcentaje, afecta negativamente sus propiedades mecánicas. En conclusión, el “concreto permeable” se sitúa dentro de los rangos establecidos según normativa: 17.5 MPa, 2.6 MPa, 6.1 mm/s, respectivamente; por ende, adquiere un valor sustancial, contribuyendo con la mejora del nivel microestructural y mayor durabilidad, siendo ventajoso y útil en los tiempos modernos.

“…Different materials with binder properties have been studied to serve as replacement to OPC as eco-friendly economic development of concrete has remained prime target of researchers to follow the circular economy principles. Different materials like RHA, FA, SF, BA, NL, SBR, BOFS, GGBFS and different other materials have been tested for utilization of raw materials as binder [ 56 , 70 , 72 , 92 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 , 212 , 213 , 214 , 215 , 216 , 217 , 218 , 219 , 220 , 221 , 222 , 223 , 224 ].…”

Polymer composites have been identified as the most innovative and selective materials known in the 21st century. Presently, polymer concrete composites (PCC) made from industrial or agricultural waste are becoming more popular as the demand for high-strength concrete for various applications is increasing. Polymer concrete composites not only provide high strength properties but also provide specific characteristics, such as high durability, decreased drying shrinkage, reduced permeability, and chemical or heat resistance. This paper provides a detailed review of the utilization of polymer composites in the construction industry based on the circular economy model. This paper provides an updated and detailed report on the effects of polymer composites in concrete as supplementary cementitious materials and a comprehensive analysis of the existing literature on their utilization and the production of polymer composites. A detailed review of a variety of polymers, their qualities, performance, and classification, and various polymer composite production methods is given to select the best polymer composite materials for specific applications. PCCs have become a promising alternative for the reuse of waste materials due to their exceptional performance. Based on the findings of the studies evaluated, it can be concluded that more research is needed to provide a foundation for a regulatory structure for the acceptance of polymer composites.

“…The UPV method could be also used to determine material constants (e.g., modulus of elasticity [ 17 ]) or detect defects such as voids, delamination or cracks [ 18 , 19 , 20 , 21 ]. The usefulness of the UPV method in testing of polymer or polymer–cement composites has been demonstrated too [ 21 , 22 , 23 , 24 , 25 , 26 ].…”

In this paper an analysis of the influence of polymer concrete sample shape and dimensions on ultrasonic wave propagation is carried out. Compositions of tested fly ash polymer concretes were determined using a material optimization approach. The tests were carried out on the samples of three shapes: cubes, beams, and plates. The ultrasonic testing was done by a direct method (transmission method) using a digital ultrasonic flow detector and piezoelectric transducers of 100 kHz central frequency. Propagation of the ultrasonic wave was characterized by pulse velocity. Frequency spectra and time-frequency spectrograms obtained using Fourier transform and Fourier-based synchrosqueezing transform were also presented. The correlation analysis showed that neither the path length nor the lateral dimension to the direction of wave propagation are not statistically significant for the UPV variability. However, a general trend of decrease in the UPV with increasing the path length was noticed. The analysis of the signal in time-frequency domain seemed to be useful in the analysis of particulate composites properties, especially when UPV changes are not clear enough, since it revealed greater differences in relation to changes in sample geometry than frequency spectra analysis.
