    • In situ chemical modification of C–S–H induced by CO2 laser irradiation 

      Martínez Ramírez, Sagrario; Díaz Sol, Luis M.; Martín Garrido, Moisés; Fernández Carrasco, Lucía; Torrens Martín, David (2018-02)
      Article
      Accés obert
      Fire-induced compositional changes lead to strength loss and even failure in cement and concrete. Calcium silicate hydrate (C–S–H) gel, the main product of cement hydration, dehydrates at 25–200 °C, while temperatures of ...

    • Infrared and Raman vibrational modelling of ß-C2S and C3S compounds 

      Timón Salinero, Vicente; Torrens Martín, David; Fernández Carrasco, Lucía; Martínez Ramírez, Sagrario (2023-07)
      Article
      Accés obert
      Density Functional Theory was applied to obtain a refined IR and Raman theoretical vibrational spectra of the major silicate phases of Portland cement, i.e. dicalcium silicate (ß-C2S) and tricalcium silicate (C3S). We ...

    • Infrared spectroscopy in the analysis of building and construction materials 

      Fernández Carrasco, Lucía; Torrens Martín, David; Morales, L.M.; Martínez Ramírez, Sagrario (Intech, 2012-03-30)

    • Nonwoven flax fiber mats and white portland cement composites for building envelopes 

      Fernández Carrasco, Lucía; Claramunt Blanes, Josep; Llerena Encalada, Ana; Torrens Martín, David; Ardanuy Raso, Mònica; Zamora i Mestre, Joan-Lluís (International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Traditionally, architectural materials performance was the key point for developing materials; but nowadays, other criteria’s as sustainability, availability and recyclability are being considered. By the other hand, the ...

    • Raman Spectroscopy of Anhydrous and Hydrated Calcium Aluminates and Sulfoaluminates 

      Torrens Martín, David; Fernández Carrasco, Lucía; Martínez Ramírez, Sagrario; Ibáñez, Jordi; Artús, Lluís; Matschei, Thomas (2013-10-04)
      Article
      Accés restringit per política de l'editorial
      Recent investigations have revealed the great potential of Raman spectroscopy for the characterization of clinker minerals and commercial Portland cements. The usefulness of this technique for the identification of anhydrous, ...

    • Up to 100% replacement of natural materials from residues: recycling blast furnace slag and fly ash as self-leveling cementitious building materials 

      Torrens Martín, David; Fernández Carrasco, Lucía; Blanco Varela, M.Teresa (Multidisciplinary Digital Publishing Institute (MDPI), 2023-05)
      Article
      Accés obert
      The objective of this research is to study the use in the construction industry of recycled slag (SL) and fly ash (FA) using from 0.1 to 5% calcium sulfate (wCS¯). These wastes have been used to make ternary mixture systems ...
