      Conference lecture
      Open Access
      Polyester (PET) materials have become more common as reinforcement solution in reinforced soil walls (RSW). It has been shown that strength and stiffness of geosynthetics products, including PET, is load-, time-, and ...

    • Soil biostabilisation and interaction with compaction processes for earthen engineering structures production 

      Bernat Masó, Ernest; Gil Espert, Lluís; Lis Arias, Manuel José; Teneva, Elitsa (2021-08-17)
      Article
      Open Access
      Interaction between microbially induced calcium carbonate precipitation (MICP) and compaction procedures to stabilise raw soil materials has been studied with the aim of producing earthen engineering structures. Initial ...

    • Soil stabilization using waste paper fly ash: precautions for its correct use 

      Baloochi, Hani; Aponte Hernández, Diego Fernando; Barra Bizinotto, Marilda (2020-12)
      Article
      Open Access
      This paper deals with the valorization of waste paper fly ash (WPFA) as a binder for soil stabilization. The mineralogical characterization shows the presence of free lime, as well as some non-reactive and cementitious ...
