2019-4-21 mainly due to the attached mortar paste on recycled concrete particles. Recycled aggregates have been found to have high water absorption capacity, which affects various properties mainly mechanical performance of the resulting concrete mix. Based on previous research, this paper presents a comprehensive overview of the recycled concrete material characteristics and the effect

2003-2-1 Assessment of the influence on durability induced by the features of recycled aggregate and the overall quality of RAC. Recycled aggregate cannot be considered as inert. They are highly heterogeneous and porous, as well as a high content of impurities. The main drawback of RAC is the difficulty in obtaining a good workability.

As more than 50% construction and demolition (CD) wastes are composed of concrete debris in Hong Kong, recycling this debris into Recycled Aggregate (RA) for production of Recycled Aggregate Concrete (RAC) is an efficient way to alleviate the burden on landfill areas. Since RA is generated from concrete debris which has undergone years of services, the resulting RAC bears the weaknesses of ...
