Abstract
This work aims at the characterization of the clay of the locality of Dolisie for its valorization. The mineralogical analysis was determined by the following techniques (DRX, IR, ATG and ATD), chemical analysis was determined by ICP-AES, CEC was assessed by the Metson method. The geothermal properties were determined by the granulometric analysis of the clay soil and allowed us to position the Dolisie clay in the texture triangle, the landings limits obtained allowed to place the Dolisie clay in the abacus of Casagrande and on the workability map of Bain and Highy. Chemical analysis showed that silica alumina as well as iron oxides are the major constituents in Dolisie clay The mineralogical balance showed that kaolinite and illite have similar percentages which are (20.51%) kaolinite, (28.08) illites. This leads us to believe that kaolinite is not the dominant mineral and the IR spectrum shows that kaolinite is poorly crystallized.

By comparing the spectrum of Dolisie with that of mouyoudzi whose kaolinite is the dominant mineral in the range from 3100 cm−1 to 3700 cm−1 (Figure 5 and Figure 6), we find that our Dolisie spectrum shows only two bands of kaolinite instead of four bands we can say that the kaolinite of Dolisie clay is not very crystallized because for a well crystallized kaolinite we have the presence of four (4) bands [5]
Summary
Clays are natural minerals that have been used by humans for millennium due to their abundance. The characterization of a clay could allow its recovery It is with this in mind that a research program has been set up for the characterization of various clay materials present in the Republic of Congo, with a view to their valorization. Several Congolese localities have already been characterized in particular Loutété, Loukoléla, mouyoundzi, Makonongo and londélakayes and many others [3] [4] [5] [6] [7]. Mouyoundzi, Makonongo and londé-lakayes could be used in ceramics. It is with this in mind that we have chosen to mineralogically and physically characterize the clay soil sampled in the Niari region in order to predict its future use and to understand why this soil is used by the local population for consumption
