Study on Crack Behavior of Recycled Fine Aggregate Concrete under Axial Compressive Load

Abstract:

In order to effective utilize of recycled fine aggregate concrete (RFAC), it is necessary to clearly understand its behavior and characteristic. In this paper, experimental study on crack behavior of RFAC was conducted with different curing ages. Ratio of its cracking load to ultimate load was analyzed in detail. Experiment shows that this ratio is about 0.8 and is not sensitive to curing age. Comparison to traditional concrete was performed. The result of this paper is helpful to theoretical analysis and practical engineering design of RAC structures.
