Mineralogical and Physicochemical Characterization of the Clay Soil in the Locality of Loukolela (Congo)
摘要
The objective of this study is to characterize the clay of the locality of Loukolela. The mineralogical analysis is given by using different techniques (DRX, IR, DTA, TGA, DTG). Among the physico-chemical properties, the chemical analysis is given by using the procedure of Carignan by proportioning each oxide by ICP-AES, the CEC is evaluated by the method of Metson. The properties of surface and the mesoporosity are deduced from the isotherm of adsorption/desorption of nitrogen on LOUK2 sample. The geotechnical properties of this soil are highlighted by determining the particle-size distribution of the soil by the method of sedimentation and sifting and the determination of the Atterberg limits. The potential of swelling is estimated by empirical methods. The mineralogical composition obtained and the physicochemical properties have revealed the predisposition factors of the shrinkage-swelling phenomenon. The estimated swelling potential allowed to classify the soil of the bank of the Loukolela as a swelling clay.
