“…Gokce et al (137) studied the soundness of coarse RCA, sourced from concrete specimens with different compressive strengths and subjected to varying processing stages, exposed to a sodium sulphate solution. The mass loss of RCA was mainly governed by the adhered mortar content (i.e.…”

“…Son diversos los países que permiten y regulan el uso de áridos reciclados de hormigón en este tipo de aplicaciones, por lo que existen diversas publicaciones que han estudiado la durabilidad de los hormigones que incorporan este tipo de árido frente a condiciones atmosféricas caracterizadas por bajas temperaturas. Algunos autores [2][3][4] han sostenido un peor desempeño de los hormigones debido a la presencia de mortero adherido, especialmente cuando su procedencia es un hormigón original elaborado sin aditivos aireantes [5], o a la saturación total de los áridos reciclados, con el objetivo de alcanzar unas consistencias adecuadas [6]. Sin embargo, Yildirim et al [7] y de Oliveira and Vazquez [8] observaron mejoras en el comportamiento del material frente a este tipo de condiciones atmosféricas cuando los áridos reciclados se incorporan a la mezcla en un estado de saturación parcial.…”

“…Another study by Gokce et al (40) resulted in poor resistance of RAC with coarse aggregate derived from non-air-entrained concrete. RAC made with recycled coarse aggregates that originated from air-entrained concretes was highly frost resistant and showed freeze-thaw resistance that was superior to that of normal concrete after subjected in 500 freezing and thawing cycles (40).…”

“…Another study by Gokce et al (40) resulted in poor resistance of RAC with coarse aggregate derived from non-air-entrained concrete. RAC made with recycled coarse aggregates that originated from air-entrained concretes was highly frost resistant and showed freeze-thaw resistance that was superior to that of normal concrete after subjected in 500 freezing and thawing cycles (40). However, Zaharieva et al (41) showed that RAC had lower resistance to freezing and thawing than normal concrete due to the higher porosity and poorer mechanical characteristics of RAC (42).…”
