Abstract

 The objective of this work is to study the mechanical and hydraulic behavior of soil-cement bentonite (SCB) and soil-bentonite (SB) mixtures when permeated with water and diesel oil, as well as to investigate the influence of cement content with the purpose of providing results capable of helping in the design of vertical cutoff walls. The experimental program was based on unconfined compression tests, hydraulic conductivity tests and X-ray diffraction tests. The analysis of the results allowed identifying changes in hydraulic conductivity due to the variation of the water-cement ratio and permeant fluid.
