Etude de la degradation des grains sous des conditions climatiques simulees : calculde leur dimension fractale

Abstract EN

Influence oflce Watch of climatic conditions was carried out by a series of alteration test (freeze / thaw test, degradability test and alterability test) for 3 types of rock (marl, schist and sandstone).

The deterioration of the grains was evaluated by the concept f fractal dimension, which measures the degree of irregularity or fragmentation of the grains.

Analysis of the results shows that the marl is a degradable rock, sensitive to water conditions, particularly to freeze-thaw conditions, against, the sandstone is not degradable and insensitive to these conditions and the sha.1e is a rock has inter-mediate characteristics.
