Abstract:
Authors studied the effects of the recycled fine aggregate(RFA)replacement ratio on compressive strength of recycled concrete through cubic compressive strength experiment. The result shows that there is little effect on the compressive strength of recycled concrete when the RFA replacement ratio is less than 30%; the compressive strength of recycled concrete is reduced when the RFA replacement ratio is more than 30%. When the RFA replacement ratio is 100%, the compressive strength of recycled concrete is 61% than that of ordinary concrete. There is a significant change in the discreteness of the compressive strength of recycled concrete after the RFA is mixed. The standard deviation of the compressive strength of recycled concrete is between 1.36 MPa and 4.17 MPa when the RFA replacement ratio varies from 0% to 100%.
