Analysis of sand samples reveals differing clay content and grain sizes between two urban municipalities, indicating diverse soil compositions.
This research is part of a technical granulometric study of a sand sample from the municipality of Kissidougou and the urban municipality of Faranah. The results of the survey show that the sand sampled in Kissidougou is estimated at 71.5% and that of Faranah at 71.36%. However, 1.39% clay was found in Kissidougou compared to 0.38% in Faranah, which proves that the soil is more clayey in Kissidougou than in Faranah. Therefore, this study also allowed us to describe and perform a granulometric analysis in order to determine the weight proportions of grains of different sizes in the sand from these two cities. Furthermore, it helped us to characterize the sand, evaluate its quality for specific fine applications, such as in construction and as fill for uneven terrain, and deduce information about its geological origin and environment.
