Abstract
In order to investigate the influence of hydrogen-ion concentration exponent on engineering properties of bentonites, unconfined compression tests and oedometer tests have been performed on bentonites with different hydrogen-ion concentration exponent and consolidation time.
As a result, a different pattern of consolidation curves was produced for a variation of hydrogen-ion concentration exponent. In addition, strength and deformation characteristics of the samples depend on the hydrogen-ion concentration exponent and consolidation time. The reason for this may be considered that different soil structures were developed with different hydrogen-ion concentration exponent and consolidation time. Hydrogen-ion, concentration exponent, therefore, is one of the most important factors in considering engineering properties of bentonites.
