It is important for geotechnical engineers to understand the intrinsic and mechanical behaviour of silt as it is presently recognised that there exist gaps in understanding its fundamental behaviour. The behaviour of kaolin samples with varying clay and silt contents was investigated in the present study. This study characterised the samples by their corresponding ranges of plasticity index (P I ) -namely, P I £ 13% and P I > 13%. This outcome is achieved by interpreting the results of Atterberg limit tests, particle size analysis, isotropically consolidated undrained triaxial tests and oedometer tests carried out on the kaolin samples with P I between 7 and 16%. The results obtained in this study show good reliability when compared to 65 sets of past significant experimental studies derived from 33 established past research papers.

In this research, the physical properties and stress paths of commercially available Malaysian kaolinite silts have been made available for laboratory testings. Properties and behavior of the kaolinite silts with varying clay contents have been studied in terms of particle size distribution, Atterberg limits and consolidated isotropic undrained (CIU) triaxial tests. Through understanding the physical and mechanical properties of the kaolinite silts, the results will form baseline data for the study of riverbank soils of Sarawak, which are dominated by similar high plasticity soft silts. Linear but inversely proportional relationships have been established between the effective angles of internal friction and the Atterberg limits. Hence, the designers may use the established equations to estimate the preliminary effective angle of internal friction if the only available data is Atterberg limits.

“…Pore shrinkage in the consolidation process would be accordingly changed to further affect the soil mechanic behavior which related to the type and intensity of pressure [1]. It is well known that drainage paths are primarily controlled by pressure, and clay-rich soils contain a network of pores on different scales.…”

Abstract:The microstructure porosities and pore size distribution of the clayey soil in the Pearl River Delta were studied by techniques of Scanning Electron Microscopy (SEM) and pressure gradient method. It was found that small pores were increased with increasing of the loading of clay samples. On the other hand, large pores with diameter of over 4μm were obviously decreased with increasing the loadings because of the squeeze effect to cause the large pores to be broken into smaller ones. The loading amount was investigated based on the stress change to improve the efficiency of saturated clayed soil foundation treatment. The effect of stress distribution on mechanical properties in the consolidation process was also investigated through the rate of anisotropy characteristics in the same full of saturated soft clay. The maximum principal stress and pore size with short axis angle were reduced.
