Abstract
In this paper, the strength and compressibility of a reference material such as Kaolin clay after treatment with binders was studied with the aim of identifying key behavior features and differences with respect to noncemented Kaolin clay. The water content of the soil was fixed at a high value to represent a very soft consistency. Portland cement was used as binder at dosages varying from 5% to 20%. A number of samples were prepared in the laboratory and were allowed to cure under controlled conditions. The shear and compression behavior of natural and cement-treated kaolin clay samples was assessed by triaxial compression testing and oedometer tests. The results demonstrated that cemented samples show initially much higher stiffness and strength than noncemented samples. But as the stress level increases a yielding state is encountered where interparticle bonding begins to break intensively. Before yielding (at low stresses), the strength is governed by the cement dosage and the one-dimensional compression is almost negligible. Beyond yielding (at high stresses) the strength is governed by the stress level just like for any frictional material. Under onedimensional compression, a clear collapse is observed; the compression lines tend towards the compression line of the noncemented clay with a gradient that lightly steepens with increasing cement dosage.
