Answer:
Explanation:
In this study, fractal analysis and 3D X-ray computed tomography accompanied by digital image analysis technique are used for the quantitative evaluation of segregation resistance, static strength and corrosion-induced cracking in normal self-compacting concrete and self-compacting lightweight concrete. From image analysis performed on the vertical sections of the specimens, it was observed that self-compacting lightweight concrete had much higher resistance to segregation and the use of coarse lightweight particles in self-compacting concrete did not contribute to extensive level of anisotropy. The results also indicate that self-compacting lightweight concrete was weaker in compression than normal self-compacting concrete mainly due to less homogeneous internal structure. Finally, it was also shown that self-compacting lightweight concrete had lower susceptibility to corrosion in the early stage of exposure to the chloride environment than normal self-compacting concrete and greater fractal energies were dissipated in self-compacting concrete made with less porous and stiffer conventional aggregates.
