ABSTRACT
A set of 1D compression tests were conducted for marine coral sand with different fines content to investigate the variations of particle breakage ratio, fractal dimension, and the relationship between them. Test results reveal that coral sand with lower fines content in a loose state are more susceptible to breakage. Furthermore, the fractal dimension exhibits a rapid increase with the rising fines content, followed by a gradual growth as the fines content continues to increase. Nevertheless, a combination of high relative density and larger medium particle size contributes to a reduction in fractal dimension. In conclusion, a proposed relationship between particle breakage ratio and fractal dimension is presented.
