Influence of chloride and sulfate ions on the geotechnical properties of soils treated with hydraulic binders
The reuse of soils after adding binder agents results in the improvement of their physical and mechanical characteristics, allowing them to be reused in several geotechnical applications. Our ongoing research work is aiming at assessing the influence of chloride and sulfate ions, introduced as NaCl and CaSO4·2H2O, on physical and mechanical properties of treated soils.
At 10 g·kg−1 of dry soil, the chloride ions’ presence can affect the stabilisation process of treated soils with hydraulic road binder, but the strengths are still suitable for a reuse in sub-base layer. With the same content, sulfate ions can generate an important swelling, along with losses of strengths during suitability tests. In standard cure, these losses are less severe.
