An experimental study on the effect of recycled aggregate on concrete properties

摘要

In this experimental study, the effect of the recycled aggregate on interfacial property, permeability and strength characteristics of the concrete was evaluated in order to examine the relationship between the recycled aggregate and the performance of the hardened concrete. Five types of recycled aggregate and four levels of w/c ratio were tested. The effect of the recycled aggregate was evaluated using Vickers hardness test of aggregate interface, carbonation depth test tensile strength test, and compressive strength test. The experimental results showed that the recycled aggregate has a significant effect on the overall properties of concrete.
