Variation of the Hydraulic Conductivity and the Mechanical Characteristics of Plastic Concrete with Time

Abstract Sand-bentonite-cement are commonly used as cut-off walls to isolate polluted soils or in ground improvement technologies and retaining structures secant pile wall. In this research, a laboratory program consisted from 105 sample were prepared tested between different tests, such hydraulic conductivity, porosity, compressive strength monitor the mechanical behavior of sand-bentonite-cement at ages. Based on experimental relationships conductivity coefficient samples age; there reduction due added bentonite mixture reach about 35.0% 7 days. Moreover, average plastic concrete with was lower by range 51.0% than without study, proposed formulas derived estimate splitting tensile based terms bentonite/cement ratio testing age. The predicted values showed well agreement records for mixtures where standard deviation variation 0.02, 0.94%, respectively.
