Disposal and treatment of construction and demolition (C&D) wastes are often costly and hazardous to the environment. Their recycling could lead to a greener solution to the environmental conservation. This study utilizes demolished concrete as coarse aggregate often termed as recycled coarse aggregate (RCA) for producing industry quality concrete. Large scale recycling can substantially reduce the consumption of natural aggregate and help preserve the environment. However, in near future, it can raise new challenges. The use of “repeated recycled coarse aggregate” in concrete production can be a viable solution to the growing problem regarding the Construction & Demolition waste disposal. During the development of new generation product like recycled and repeated recycled coarse aggregate concrete, it is essential to investigate the fresh, hardened, and durability properties of concrete to promote and escalate its application in the construction industry. Through adding kenaf fiber into the mixture, it may have prospect to prevent the cracking beams. Four beams are constructed in this research, which are the control beam and the rest beams replaced with 25% of recycled concrete as coarse aggregate added with (0%,1%,2%) volume of kenaf fibers. Kenaf fiber had potential to delay the cracking compared to control beam. However, kenaf fiber reinforced recycled aggregate concrete beams has potential to become more ductility compare with control beam.
