Abstract

This work proposes the studying of characterization analysis of two natural Moroccan clays (RC and GC) in the same location from Bejaad (Province of Khouribga, Morocco) and to know the relationship dependence between them. The values obtained during the determination of a few parameters (density, pH, conductivity, dry matter - moisture content, organic matter-mineral matter) show that the two materials RC and GC studied have the same physical-chemical properties. The all characterization of the two clays was carried out by XRD, XRF, FTIR, SEM/EDX and TGA. The results obtained show that the two materials have very irregular and microporous structures, a heterogeneity of the pore forms and they are contain a mixture of Kaolinite, Illite, Quartz, Calcite, and Dolomite, with the presence of Hematite only in clay RC. On the other hand, The statistical approach applied to determine the dependence relationship between the two clays was based on two tests: Student's t-test (Comparison of two means for physical-chemical parameters) and Pearson's test (contingency table for XRF analysis) in order to prove that the two materials studied are the same chemical and physical-chemical characteristics.
用统计方法研究贝加德省(摩洛哥中部)两种最丰富的天然粘土之间的依赖性
本文拟对来自摩洛哥库里布加省贝加德同一地点的两种天然摩洛哥粘土(RC和GC)进行表征分析,并了解它们之间的依赖关系。密度、pH、电导率、干物质-水分含量、有机质-矿物质等参数的测定结果表明,RC和GC所研究的两种材料具有相同的物理化学性质。通过XRD、XRF、FTIR、SEM/EDX和TGA对两种粘土进行了表征。结果表明:两种材料具有非常不规则的微孔结构,孔隙形态不均匀,主要由高岭石、伊利石、石英、方解石和白云石混合组成,赤铁矿仅在粘土RC中存在。另一方面,采用统计方法确定两种粘土之间的依赖关系是基于两个检验:学生t检验(物理化学参数的两种平均值的比较)和Pearson检验(XRF分析的列联表),以证明所研究的两种材料具有相同的化学和物理化学特性。
