    • Characterization of biomass briquettes from spent coffee grounds and xanthan gum using low pressure and temperature 

      Seco Meneses, Andrés Upna Orcid; Espuelas Zuazu, Sandra Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; Echeverría, Angel María Upna Orcid; Prieto Cobo, Eduardo Upna Orcid (Springer, 2020)   Artículo / Artikulua  OpenAccess
      This paper analyzes the ability of the SCG for briquettes production based on the use of xanthan gum as binder under low-pressure and low-temperature biomass manufacturing conditions. Briquettes were manufactured at room ...
    • Characterization of fresh and cured properties of polymer concretes based on two metallurgical wastes 

      Seco Meneses, Andrés Upna Orcid; Echeverría, Angel María Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; García, Beñat; Espuelas Zuazu, Sandra Upna Orcid (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      Polyester polymer concretes can substitute conventional concretes based on their usually good mechanical strength, adequate physical properties, and high resistance against aggressive chemical environments. They also show ...
    • Durability of polyester polymer concretes based on metallurgical wastes for the manufacture of construction and building products 

      Seco Meneses, Andrés Upna Orcid; Echeverría, Angel María Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; García, Beñat; Espuelas Zuazu, Sandra Upna Orcid (Elsevier, 2020)   Artículo / Artikulua  OpenAccess
      Varied target materials can be incorporated into polyester polymer concretes (PPC). This allows natural aggregates to be substituted for different waste products in non-structural polymeric construction and building ...
    • Low energy spent coffee grounds briquetting with organic binders for biomass fuel manufacturing 

      Espuelas Zuazu, Sandra Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; Echeverría, Angel María Upna Orcid; Castillo, Jesús María del Upna Orcid; Seco Meneses, Andrés Upna Orcid (Elsevier, 2020)   Artículo / Artikulua  OpenAccess
      This paper analyzes the ability of the spent coffee grounds (SCG) for briquettes production with xanthan and guar gums as binders. Briquettes were manufactured at room temperature, at 15%, 20%, 25% and 30% of moisture, at ...
    • Magnesium oxide as alternative binder for unfired clay bricks manufacturing 

      Espuelas Zuazu, Sandra Upna Orcid; Omer, Joshua; Marcelino Sádaba, Sara Upna Orcid; Echeverría, Angel María Upna Orcid; Seco Meneses, Andrés Upna Orcid (Elsevier, 2017)   Artículo / Artikulua  OpenAccess
      Replacement of fired bricks by unfired ones could be an effective way to reduce the building industryenvironmental footprint: Their manufacture not only requires less energy and natural resources but alsogenerates less waste. ...
    • Technical and environmental characterization of hydraulic and alkaline binders 

      Espuelas Zuazu, Sandra Upna Orcid; Echeverría, Angel María Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; Prieto Cobo, Eduardo Upna Orcid; Seco Meneses, Andrés Upna Orcid (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      Portland cement is a widely used binder in construction and building applications because of its good properties. Despite its convenience as construction material, the social demands and policies trends are requesting a ...
