THE EFFECT OF THE COLLOIDAL CLAY CONTENT ON THE SWELLING AND PLASTICITY BEHAVIOR

Published in Journal of Young Scientist, Vol.I
Written by George Marian DASCALU, Alex Nicolae VADUVA

Clayey soils are soils with high shrink-swell potential. This soils have the property to significantly modify their volume when moisture changes. The magnitude of dry contraction and moisture swelling increases with the colloidal clay content. Minerals of the kaolinite group are the least active, while the montmorillonites are the most active. As shown by tests, the swelling potential and the plasticity of clays are high in clay of the montmorillonite type (bentonite) and rise with the fine-fraction content.
