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

      Seco Meneses, Andrés Upna; Espuelas Zuazu, Sandra Upna; Marcelino Sádaba, Sara Upna; Echeverría, Angel María Upna; Prieto Cobo, Eduardo Upna (Springer, 2020)   Artículo / Artikulua
      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; Echeverría, Angel María Upna; Marcelino Sádaba, Sara Upna; García, Beñat; Espuelas Zuazu, Sandra Upna (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; Echeverría, Angel María Upna; Marcelino Sádaba, Sara Upna; García, Beñat; Espuelas Zuazu, Sandra Upna (Elsevier, 2020)   Artículo / Artikulua
      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 ...
    • Magnesium oxide as alternative binder for unfired clay bricks manufacturing 

      Espuelas Zuazu, Sandra Upna; Omer, Joshua; Marcelino Sádaba, Sara Upna; Echeverría, Angel María Upna; Seco Meneses, Andrés Upna (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. ...
    • Sustainable unfired bricks manufacturing from construction anddemolition wastes 

      Seco Meneses, Andrés Upna; Omer, Joshua; Marcelino Sádaba, Sara Upna; Espuelas Zuazu, Sandra Upna; Prieto Cobo, Eduardo Upna (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      The management of construction and demolition wastes is a huge challenge for most Governments. Thegreatest component of such wastes is concrete and masonry fragments or remains. Among the most com-mon approaches to ...
    • Technical and environmental characterization of hydraulic and alkaline binders 

      Espuelas Zuazu, Sandra Upna; Echeverría, Angel María Upna; Marcelino Sádaba, Sara Upna; Prieto Cobo, Eduardo Upna; Seco Meneses, Andrés Upna (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 ...
