    • Recycling silicon solar cell waste in cement-based systems 

      Fernández Carrasco, Lucía; Ferrer, R.; Aponte Hernández, Diego Fernando; Fernández, P. (2011-03-03)
      Article
      Restricted access - publisher's policy
      This is a study of the recycling of crystalline solar cells by incorporating them in cement matrices. The hydration process of a mixture of calcium aluminate cement (CAC) and solar photovoltaic cell waste was researched ...

    • Rheological behavior of recycled aggregate concrete 

      Barra Bizinotto, Marilda; Aponte Hernández, Diego Fernando; Faleschini, Flora; González Fonteboa, Belen; González Taboada, Iris (Elsevier, 2021)
      Part of book or chapter of book
      Restricted access - publisher's policy
      This chapter presents the rheological study of the two main types of recycled aggregate concrete mixes (normal consistency and self-compacting). The concepts of rheology and its applications to recycled concrete are ...

    • Rheology of fresh concretes with recycled aggregates 

      Faleschini, Flora; Jiménez Fernández, Cristian Gonzalo; Barra Bizinotto, Marilda; Aponte Hernández, Diego Fernando; Vázquez Ramonich, Enric; Pellegrino, Carlo (2014-12-30)
      Article
      Restricted access - publisher's policy
      The most frequently used measure of rheology is the slump test, which evaluates workability. Since this value is often operator-sensitive, a more quantitative estimate can be derived in terms of fundamental physical ...

    • 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 ...

    • Stabilization of photovoltaic panels cell wastes in building material matrices 

      Fernández Carrasco, Lucía; Ferrer, Rober; Aponte Hernández, Diego Fernando; Martínez Ramírez, Sagrario (Consejo Superior de Investigaciones Científicas (CSIC), 2009)
      Conference report
      Open Access
      This is a study about the hydration process of a mixture of Portland cement and solar photovoltaic cells waste. The nature of the hydration products of different compositions of these mixtures have been evaluated, at 20º ...

    • Study of adhesion between steel slag aggregates and bitumen taking into consideration internal factors influencing moisture damage 

      Benavides Alcívar, Julio Darío; Aponte Hernández, Diego Fernando; Barra Bizinotto, Marilda; López Montero, Teresa (2023-02)
      Article
      Restricted access - publisher's policy
      Electric arc furnace slag (EAFS) has been proposed as a replacement in hot-mix asphalt. This work compares the physical-chemical-mineralogical and morphological factors involved in the moisture damage of natural aggregates ...

    • Transport of moisture and chlorides into sprayed concrete 

      Aponte Hernández, Diego Fernando; Barra Bizinotto, Marilda; Valls del Barrio, Susanna; Fernández Carrasco, Lucía (2020)
      Conference report
      Open Access
      This contribution is a study of the durability and transport properties of sprayed concrete used in an actual construction site. It considers whether concrete spraying can generate different porosities as the thickness of ...

    • Utilización de áridos reciclados "una oportunidad oportunidad frente a la situación actual" 

      Barra Bizinotto, Marilda; Aponte Hernández, Diego Fernando; Pielarisi, Sergio Henrique; Valls del Barrio, Susanna; Vázquez Ramonich, Enric (Universitat Politècnica de Catalunya. Escola Tècnica Superior d'Enginyers de Camins Canals i Ports de Barcelona, 2011-11-16)
      Conference lecture
      Open Access
      El impacto ambiental de la explotación de recursos naturales y el consumo desmedido de territorio con los vertederos impulsa la obtención y aplicación de áridos reciclados. El objetivo de los trabajos de nuestro equipo ...

    • Waste paper ash as an alternative binder to improve the bearing capacity of road subgrades 

      Cepriá, Juan José; Orejana Gonzalez, Roberto; Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée; Barra Bizinotto, Marilda; Aponte Hernández, Diego Fernando; Baloochi, Hani (Taylor & Francis, 2022)
