Chemical and mineralogical behaviour of lignosulfonate treated soils

Conference Paper


Abstract


  • This paper presents the results of Unconfined Compressive Strength tests (UCS)

    carried out on clay soils stabilized with Lignosulfonate (LS). Laboratory studies

    indicate that lignosulfonate can increase the stiffness of the treated soils. Moreover,

    the influence of clay minerals on the LS stablisation is investigated using Fourier

    Transform Infrared (FTIR) Spectroscopy and Electrical Conductivity (EC). The

    analysis confirms that the clay mineralogy plays an important role in the stabilisation

    of clay soils. The stabilization mechanism is mainly due to the formation of

    lignosulfonate-clay amorphous compounds through the electrostatic reaction process.
