| dc.description.abstract | This paper presents an experimental study to evaluate the influence of adding 5% of cement, by dry mass of soil, on the strength and deformability of two different clays. Oedometer tests were performed on specimens of the two different clayey soils, low plasticity Portugal clay and high plasticity Pljevlja clay, compacted according to standard Proctor test. Adding cement to the specimens resulted in reduction of instantaneous and time-dependent deformations under oedometric conditions. The increase in the preconsolidation stress, as determined by the oedometer test, along with the foregoing, indicates that adding cement has the similar effect as pre-consolidate of the clay. Conventional triaxial compression tests (CU) were performed on specimens of Portugal clay. The results of these tests showed that, with added cement, the compressive strength and secant Young's modulus E50 increases. Results of the CU tests indicated also that, once the cement is added, the soil behaviour changes from plastic to brittle plastic along with the pore pressure dropping during the shear stage. | en |
