      Accés restringit per política de l'editorial
      The Iberian Pyrite Belt (IPB), SW Spain and Portugal, contains about 100 abandoned mine wastes and galleries that release acid mine drainages (AMD) to the Tinto and Odiel rivers. In situ passive remediation technologies ...

    • Ammonium N-(pyridin-2-ylmethyl)oxamate (AmPicOxam): a novel precursor of calcium oxalate coating for carbonate stone substrates 

      Pintus, Anna; Aragoni, M. Carla; Carcangiu, Gianfranco; Caria, Veronica; Coles, Simon; Dodd, Eleanor; Giacopetti, Laura; Gimeno Torrente, Domingo; Lippolis, Vito; Meloni, Paola; Murgia, Simone; Navarro Ezquerra, Antonia; Podda, Enrico; Urru, Claudia; Arca, Massimiliano (Multidisciplinary Digital Publishing Institute (MDPI), 2023-07-30)
      Article
      Accés obert
      Ammonium N-(pyridin-2-ylmethyl)oxamate (AmPicOxam), synthesized from O-methyl-N-(pyridin-2-ylmethyl)oxamate, was spectroscopically and structurally characterized and assayed as a novel precursor for the protection and ...

    • Comportamiento al fuego de mortero con adición de polvo calizo 

      Andrade Perdrix, Carmen; Martínez Serrano, Ana María; Tenorio Ríos, Jose Antonio; Anaya Gil, Pablo (2022)
      Text en actes de congrés
      Accés obert
      Cuando la caliza es añadida al cemento como adición al hormigón como arena o árido grueso, como es el caso de hormigones autocompactantes, si el elemento sufre un fuego esta caliza se descompondrá en un entorno de temperatura ...

    • Effect of filler nature and content on the bituminous mastic behaviour under cyclic loads 

      Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée; Pérez Jiménez, Félix Edmundo; Botella Nieto, Ramón; Álvarez, Allex E. (2017-02)
      Article
      Accés obert
      The role of the filler in asphalt mixtures is particularly important because of its influence on mastic behaviour. The filler improves the resistance properties of bitumen against the action of traffic loads and temperature. ...

    • Sulfate performance of blended cements (limestone and illite calcined clay) exposed to aggressive environment after casting 

      Rossetti, Agustín; Ikumi Montserrat, Tai; Segura Pérez, Ignacio; Irassar, Egardo Fabián (2021-09-01)
      Article
      Accés obert
      This paper evaluates how early aggressive exposure affects the sulfate resistance of blended cements containing limestone filler and/or calcined clay. Mortar and cement paste specimens were elaborated with different ...

    • The effect of thermal cycles on limestone mechanical degradation 

      Villarraga Díaz, C. J.; Gasc Barbier, M.; Vaunat, Jean; Darrozes, José (Elsevier, 2018-09)
      Article
      Accés obert
      This work presents the results of an experimental program performed to study the effect of long series of moderate thermal cycles on the mechanical response of a limestone rock. Samples were exposed to more than 1000 ...
