| Abstract: | The experimental study of rebound and carbonation for recycled aggregate concrete in scale produc- tion in Yangzhou is conducted in this article. The relationship between recycled concrete rebound value and replacement ratio of recycled aggregate, the effect of coarse aggregate on rebound value, and the comparison between rebound value growth of recycled concrete and traditional concrete with time increase are discussed here. Mean while, the carbonation influencing factors of recycled concrete the carbonation resistance of recy- cled concrete with recycled second class coarse aggregate, the carbonation resistance in water, and the effect of replacement ratio of coarse aggregate and fine aggregate on the carbonation depth are analyzed. |
