| dc.description.abstract | The potential uses of coarse recycled aggregates in the composition of SCC increases the ecological value and partly solve the issues of waste disposal sites generated by construction and demolition of structures. Thus, this paper present an experimental study of SCC properties where the normal coarse aggregates were replaced by different percentages of recycled aggregates, i.e., 0% (SCC), 10% (SCCR10), 20% (SCCR20), 30% (SCCR30) and 40% (SCCR40). The results from fresh concrete (rheological properties and self-compactability) as the hardened concrete properties (compressive strength, density and dynamic modulus of elasticity), show only minor discrepancies. From the standpoint of mechanical behaviour, the results confirm the viability to incorporate coarse recycled aggregates in the SCC demonstrating the conservative character of the currently recommended limits. | pt_PT |
| dc.description.abstract | Los usos potenciales de áridos gruesos reciclados en la composición del hormigón autocompactante (SCC) aumenta el valor ecológico y en parte resuelve los problemas de los sitios de disposición de residuos generados por la construcción y la demolición de las estructuras. Por lo tanto, este trabajo presenta un estudio experimental de las propiedades de SCC en el cual los áridos gruesos naturales fueron reemplazados por distintos porcentajes de áridos reciclados, es decir, 0% (SCC), el 10% (SCCR10), el 20% (SCCR20), el 30% (SCCR30) y el 40% (SCCR40). Los resultados del hormigón fresco (propiedades reológicas y la auto-compactación), como las propiedades de hormigón endurecido (resistencia a la compresión, densidad y módulo de elasticidad dinámico), muestran sólo pequeñas discrepancias. Desde el punto de vista del comportamiento mecánico, los resultados confi rman la viabilidad de incorporar áridos gruesos reciclados en los SCC demostrando el carácter conservador de los límites actualmente recomendados. | pt_PT |
