“…Therefore, it was expected that by substituting the crushed limestone with recycled coarse aggregate, the concrete's density would be lower. The results were similar to those in Safiuddin et al (34) and Khoshkenari et al (35).…”

ABSTRACT:This research aimed to use of bagasse ash as a cement replacement in high-strength recycled aggregate concrete (HS-RAC). Crushed limestone was replaced with 100% recycled concrete aggregate (RCA) and the ground bagasse ash (GBA) was used to partially replace ordinary Portland cement (OPC) at 20, 35 and 50%wt of binder to cast HS-RAC. The results indicated that the replacing of crushed limestone with RCA had a negative impact on the properties of the concrete. Increasing the amount of GBA in HS-RAC resulted in a decrease in density and an increase in the volume of permeable pore space. The concrete mixtures prepared with 20%wt GBA replacement of OPC promoted greater the compressive strength than the conventional concrete (CT concrete) at 90 days or more. HS-RAC with GBA (up to 50%) was more durable in terms of chloride ion penetration resistance, although it had lower compressive strength than the CT concrete. RESUMEN: Influencia de la ceniza de bagazo y los áridos de hormigón reciclado en las propiedades de endurecimiento de hormigones de alta resistencia.En esta investigación se utilizó ceniza de bagazo como sustituto del cemento en hormigón de alta resistencia con áridos reciclados (HS-RAC). La piedra caliza fue sustituida por un árido 100% reciclado de hormigón y la ceniza de bagazo molida (GBA) en diferentes porcentajes (20, 35 y 50% en peso del material cementante) fue utilizada para reemplazar parcialmente al cemento Portland para producir hormigón de tipo HS-RAC. Los resultados indicaron que la sustitución de la piedra caliza molida por áridos de hormigón reciclado tiene un efecto negativo en las propiedades del hormigón. Aumentar la cantidad de GBA en el HS-RAC redujo la densidad e incrementó el volumen del espacio de los poros permeables. Las mezclas de hormigón preparadas reemplazando 20% en peso del cemento Portland por ceniza de bagazo molida presentaron mayor resistencia a la compresión que el hormigón convencional a los 90 días o más. El HS-RAC con GBA (hasta 50%) tuvo una durabilidad mayor que el hormigón convencional en términos de resistencia a la penetración de iones de cloruro, a pesar de tener una menor resistencia a la compresión.PALABRAS CLAVE: Hormigón; Árido; Resistencia a la compresión; Durabilidad; Cloruros ORCID ID: P.

“…RCA can be used as a replacement of natural aggregates in cement concrete (Berndt 2009;Dam et al 2012;Evangelistaa and de Britob 2013;Safiuddin et al 2013;Shayan and Xu 2003) or, in asphalt concrete (Arabani et al 2013;Paranavithana and Mohajerani 2006;Wong et al 2007). Marshall stability, resilient modulus and stripping potential of asphalt mixes containing RCA are found to be comparable to asphalt mix with natural aggregates (Wong et al 2007;Paranavithana and Mohajerani 2006).…”

This chapter provides an in-depth but brief overview on the possible use of various waste materials for sustainable pavement construction. It compiles a literature review on the research done on such materials and highlights the current issues. IntroductionPavement construction involves consumption of large quantity of construction materials. Some of these construction materials are available in natural form and some are manufactured (from naturally occurring raw materials). Due to the rapid growth of infrastructure, naturally available good quality construction materials are gradually becoming scarce. Consequently, there is an increase in the transportation cost for acquiring good quality materials. Thus, there is a need to develop or search for alternative materials for road construction.On the other hand, large quantity of byproducts are generated from agricultural, construction and demolition, industrial and domestic sources (Aravind and Das
