ウェブ Last Updated: 15 Jun 2023. PDF | Currently, a number of disadvantages hampers the use of recycled concrete aggregates (RCA). The current review proves that
ウェブ One such material is recycled aggregate concrete. This special issue had a good acceptation by the scientific community with several papers submitted and 7
ウェブ In this paper, a comprehensive literature review was conducted on the utilization of recycled concrete aggregate (RCA), which is the dominant construction
ウェブ An approach to closing the material circles and ensuring high-quality recycling that has already become established, especially in Switzerland, is the use of recycled aggregate concrete in building construction (Katerusha,
ウェブ In recent years, as the concepts of “zero waste” and “low carbon” gradually become hot topics, the unparalleled generation of construction and demolition (CD) waste that poses a significant obstacle to the sustainable development of the built environment has attracted a lot of attention from researchers. Whether the studies on
ウェブ Recycling is considered a waste management option, and credits through the avoided NA production and transportation are subtracted from the natural aggregate concrete (NAC) life cycle. 25-27 For instance, Blegnini
ウェブ Recycled aggregates for concrete are divided into recycled fine aggregate and recycled coarse aggregate, and require a similar level of physical properties as natural aggregate. Recycled coarse aggregate and recycled fine aggregate shall have an oven-dry density of at least 2.5 g/cm 3 and 2.4 g/cm 3 , and the

ウェブ Kou et al. ( Kou and Poon, 2013) investigated the long-term properties (up to ten years) of the outdoor exposed RAC consisting recycled concrete aggregate and fly ash as partial replacement of aggregate and cement, respectively. Four replacement ratios of FA to cement in weight, i.e. 0%, 25%, 35% and 55% were
ウェブ Recycling aggregate (RCA) was produced by using limestone-based crushed aggregate (LA) and 7-day C35 waste concrete. 0–4 and 4–22.4 aggregate groups were used on both types of aggregates. In the concrete mixtures, CEM I 42.5 R type cement and Çayırhan Thermal Power Plant fly ash were
