Open publisher page 4 citations

Abstract

The mineral composition of cohesive soil has a significant impact on its engineering and mechanical properties.There are some sophisticated methods and technology to identify clay minerals.However,the quantitative measurement of clay minerals content in soil is still a question.The paper studies the chemical and mineralogical compositions of red clays in Wuming and Guilin by means of chemical analysis,X-ray diffraction test,Bogue method and K-value method.The results show that Kaolinite,gibbsite,goethite are found in both clays and quartz is additionally found in Guilin red clay.The contents of Kaolinite,gibbsite,goethite(2mm) and goethite(2mm) are respectively equal to 74.0%,12.53%,2.22% and 8.37%in Wuming red clay.The contents of Kaolinite,gibbsite,goethite and quartz are respectively 56.59%,11.44%,15.61% and 12.45%in Guilin red clay.
