An Experimental Study on the Stabilization of Bentonite Treated with a Composite Reinforcement Made of Sand and an Ionic Soil Stabilizer

As an ionic soil stabilizer (ISS) can effectively reduce the expansive properties of bentonite and sand improve strength a rapidly thereby reducing likelihood cracks, in present study, these two methods are combined to strengthen bentonite. Different experiments carried out results confirm that proposed strategy be used this material. It is also shown sand-to-bentonite mass ratio has different effects on unconfined compressive (UCS) SB (sand strengthened) ISB (ISS-sand composite strengthened bentonite) samples. The UCS samples both attenuates significantly after one freeze-thaw cycle then display only minor changes multiple cycles.
