  • Carbonation of ternary building cementing materials 

    Fernández Carrasco, Lucía; Torrens Martín, David; Martínez Ramírez, Sagrario (2012-11)
    Article
    Restricted access - publisher's policy
    The carbonation processes of ettringite and calcium aluminate hydrates phases developed by hydration of calcium aluminate cement, fly ash and calcium sulphate ternary mixtures have been studied. The hydrated samples were ...
  • Carbonation on ternary cement systems 

    Martínez Ramírez, Sagrario; Fernández Carrasco, Lucía (2012-05-01)
    Article
    Restricted access - publisher's policy
    The main hydration reaction product in the ternary system fly ash, calcium sulphate and calcium aluminate cement (40/20/40) at 20°C is a hydrated calcium sulfoaluminate compound, an AFt phase slightly different from ...
  • Evaluation of a lime-mediated sewage sludge stabilisation process. Product characterisation and technological validation for its use in the cement industry 

    Flores, J.; Larrotcha, E.; Fos, C.; Husillos Rodríguez, N.; Granados, R.J.; Blanco Varela, M.Teresa; Cortina Pallás, José Luís; Martínez Ramírez, Sagrario; Marsal Astort, Montserrat; Guillem, Manel; Puig, J. (2012-03)
    Article
    Restricted access - publisher's policy
    This paper describes an industrial process for stabilising sewage sludge (SS) with lime and evaluates the viability of the stabilised product, denominated Neutral, as a raw material for the cement industry. Lime not only ...
  • Evolution to carbonated compounds of phases developed on ternary systems materials 

    Fernández Carrasco, Lucía; Torrens Martín, David; Morales Martínez, Laura María; Martínez Ramírez, Sagrario; Fernández, Pedro (Instituto de Ciencias de la Construcción Eduardo Torroja (ICCET), 2011)
    Conference lecture
    Open Access
    The incorporation of supplementary cementitious materials to the cement industry is an alternative to reduce consume of large amounts of raw materials and gives up a huge spectrum of blended cements that have been noted ...

    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, ...
  • Raman spectroscopy: applycation to cementitious systems 

    Martínez Ramírez, Sagrario; Fernández Carrasco, Lucía (Nova Science Publishers, 2010-12-13)
    Part of book or chapter of book
    Open Access
    Raman scattering was discovered by Krisma and Raman in 1928. Until approximately 1986, the Raman literature was dominated by physical and structural investigations, with relatively few reports of Raman spectroscopy applied ...
  • 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 ...
