“…It was provided by the Holcim Company and was sourced from the quarry of Tournai. The water absorption of this sand was 1.05% according to the standard EN 1097-6 [31], and its density was 2.66 g/cm 3 measured by helium pycnometer (Micromeritics AccuPyc 1330). The recycled sand used was provided by the Colas Company and has been produced in the recycling platform of Amiens (France).…”

“…The recycled sand used was provided by the Colas Company and has been produced in the recycling platform of Amiens (France). The density of this recycled sand was 2.54 g/cm 3 measured by helium pycnometer. It was divided into four granular fractions (0/0.63, 0.63/1.25, 1.25/2.5, 2.5/5 mm) that were remixed together with specific amounts to get a similar granular distribution than natural sand.…”

“…Los residuos de la construcción y demolición (RC&D) o escombros como son llamados en algunos países latinoamericanos, son en general materiales de desecho generados durante la ejecución de un proyecto de obra civil; incluyendo estructuras y materiales rechazados, materiales que han sido descartados, materiales que han sido utilizados y se han deteriorado, e incluso aquellos derivados de actividades de excavación y limpieza del lugar al finalizar la obra, entre otros (Torgal & Jalali, 2011) (Oikonomou, 2005) (Poon & Chan, 2007) (Lin et al, 2004) (Limbachiya et al, 2004) (Adam & Kurama, 2013).…”

“…También, resultan residuos en la demolición de edificaciones afectadas por eventos naturales como sismos, inundaciones, deslizamientos, etc. Entre los residuos se destacan, por su mayor volumen, los de concreto (Torgal y Jalali, 2011;Oikonomou, 2005;Poon y Chan, 2007). La alta demanda de agregados naturales para la producción de mezclas de concreto, como resultado del continuo desarrollo de la industria de la construcción, ha planteado el interrogante de hasta cuándo las canteras y los ríos podrán abastecer esta demanda de materias primas no renovables en países latinoamericanos como Colombia, en donde se ha estimado que cerca de 18 millones de metros cúbicos de agregados naturales son usados anualmente en la producción de 35 millones de toneladas de concreto.…”
