Different size-distribution of recycled coarse aggregates by fractal theory was studied.Concretes with different maximum particle sizes were prepared by different fractal rate aggregate gradations and the slump of concrete,compressive strength,flexural strength and split strength at 3 d and 28 d were tested.The results show that recycled aggregate concrete performance with the same fractal dimension is different when the max particle size is different.The fractal dimension of recycled coarse aggregate must ...
