Fractal Cracking Patterns in Concretes Exposed to Sulfate Attack.
TL;DR: Fractal dimensions of surface cracking patterns were determined and it was shown that the change of fractal dimensions is directly proportional to accumulation of DEF, and therefore, a simple theoretical model could be proposed to describe the micro-crack evolution in concretes under sulfate attack.

An improved box-counting method to estimate fractal dimension of images
TL;DR: In this article, an improved DBC-based approach was proposed to optimize the performance of the method in the following ways: reducing fitting errors by decreasing step lengths, considering under-counting boxes on the border of two neighboring box-blocks and making better use of all the pixels in the blocks while not neglecting the middle parts.
