      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
      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 ...
    • Feasibility of vermicomposting of spent coffee grounds and silverskin from coffee industries: a laboratory study 

      González Moreno, Miguel Ángel Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; Zaratiegui Urdin, Javier Upna; Robles Domínguez, Estrella Upna; Pérez Ezcurdia, Amaya Upna Orcid; Seco Meneses, Andrés Upna Orcid (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      In the coffee industry, several by-products are generated during the production and consumption of coffee and represent an important waste from an environmental viewpoint. For improving the knowledge about this issue, a ...
    • 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
      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. ...
    • Sulfate soils stabilization with magnesium-based binders 

      Seco Meneses, Andrés Upna Orcid; Miqueléiz Jiménez, Luis; Prieto Cobo, Eduardo Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; García, Beñat; Urmeneta, Pablo (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      Sulfate soils' stabilization is a very interesting subject with technical, economic and environmental implications. The difficulty of their stabilization is due to the fact that the usual stabilizer additives are based ...
