Review of Long-Term Deformation of Recycled Coarse and Fine Aggregate Concrete
Due to long test cycle, high cost and the complex factors, the long-term deformation properties (such as creep and shrinkage) of recycled aggregate concrete (short for RAC) are rarely reported so far. However this property is essential to fully understanding and widely applying the RAC. Base on investigation on plenty of research results of the long-term deformation of RAC, this paper systematically analyzed the effect of recycled coarse aggregate (C-RA) and recycled fine aggregate (F-RA) on creep and shrinkage performance of concrete. The analysis shows that not only the replacement proportion but also the quality level of recycle aggregate (RA) affect the shrinkage and creep properties of RAC. This outcome could serve as a basis for further research.
