Research on Performance Improvement of Confined Recycled Aggregate Concrete

Abstract:

Presently large amount of slurry are generated in natural stone processing plants with an important on the environment and humans. But relative to normal concrete, the Recycled Aggregate Concrete (RAC) has unstable properties and weaker strength. Such inadequacies can be overcome though applied the confinement to the RAC. In this paper, several reinforcement systems are introduced to be used in the RAC. Analysis showed that the strength and deformation capacity are highly increased, while the shrinkage is reduced and deformation is obviously improved.
