Mechanical behaviour of bimodal kaolin clay with aggregates

Soil structure has been recognised as a key feature in the understanding of soil’s mechanical behaviour, and research efforts have made trying to relate them. However, main difficulties encountered are that numerous factors can simultaneously affect behaviour soils. Among these factors, presence aggregates is decisive for fabric configuration bimodal The aim this paper evaluate effect on soils with no mineralogical variability. For purpose, Kaolin Clay were obtained by compaction at high stresses samples different content produced. All subjected unidimensional consolidation direct shear tests. Results showed increase macro-pores affected compressibility, decreasing pre-consolidation altering compressibility coefficients. interaction between generated an friction angles aggregates, which also impacted their volumetric during shearing. Thus, present work contributes better influenced exclusively aggregates.
