Bead-releasing agents used in the preparation of solid samples as beads for WD-XRF measurement
Gazulla Barreda, Maria Fernanda; Barba-Juan, Antonio; Orduña, Mónica; Rodrigo, Marta Wiley-Blackwell (2008)A study has been undertaken of bead-releasing agents that are widely used in preparing solid samples as fused beads for wavelength-dispersive X-ray fluorescence (WD-XRF)spectrometry measurement. The following bead-releasing ... -
Clinkers and cements obtained from raw mix containing ceramic waste as a raw material. Characterization, hydration and leaching studies
Puertas, F.; García-Díaz, I.; Palacios, Marta; Gazulla Barreda, Maria Fernanda; Gómez-Tena, Maria Pilar; Orduña, Mónica Elsevier (2010)A clinker and a cement obtained from a raw mix containing ceramic waste as an alternative raw material were characterized in the present study. Their hydration, physical-chemical properties and leaching behaviour in different ... -
Comportamiento de tejas de diferente color (rojo y paja) frente al biodeterioro
Gazulla Barreda, Maria Fernanda; Sánchez-Vilches, Enrique; González, J. M.; Orduña, Mónica Elsevier (2014)La colonización biológica es un fenómeno que afecta de forma negativa a la durabilidad de los materiales de construcción. A nivel industrial se ha observado que las tejas de color paja muestran mayor tendencia a la ... -
Determinación de carbono orgánico en materias primas cerámicas en presencia de siderita, FeCO3
Gazulla Barreda, Maria Fernanda; Gómez, Carmen M.; Rodrigo Carbonell, María Dolores; Orduña, Mónica CSIC-Consejo Superior de Investigaciones Científicas (2013-05)La materia orgánica es una de las impurezas presentes en las materias primas utilizadas en la fabricación de pavimentos y revestimientos cerámicos. Durante el proceso de cocción, el carbono orgánico (Corgánico) puede ... -
Determinación de sales solubles y eflorescencias en tejas cerámicas
Gazulla Barreda, Maria Fernanda; Gómez-Tena, Maria Pilar; Orduña, Mónica; Vicente, S.; José Luis, Amorós Albaro Sociedad Española de Cerámica y Vidrio (2010)The appearance of efflorescences constitutes a serious problem for ceramic roofing tile quality, since efflorescences affect roofing tile technical and aesthetic qualities. This paper describes a method of determining the ... -
Determination of Carbon, Hydrogen, Nitrogen and Sulfur in Geological Materials Using Elemental Analysers
Gazulla Barreda, Maria Fernanda; Rodrigo, Marta; Orduña, Mónica; Gómez, Carmen M. Wiley (2012)This article describes a series of methods developed for the determination of total carbon (CTotal), organic carbon (Corg), hydrogen, nitrogen and sulfur. The following elemental analysers were used: LECO model RC-412 for ... -
Development of a WD-XRF analysis method of minor and trace elements in liquid petroleum products
Gazulla Barreda, Maria Fernanda; Orduña, Mónica; Vicente, S.; Rodrigo, Marta Elsevier (2013)This paper describes a methodology for the analysis of minor and trace elements in liquid petroleum products, with varying oxygen content between 0% w/w and 3.4% w/w and varying C/H ratio between 7 and 9, by wavelength-dispersive ... -
Kinetic model of the dissolution process of a zirconium white frit. Influence of the temperature
Barba-Juan, Antonio; Jarque Fonfría, Juan Carlos; Orduña, Mónica; Gazulla Barreda, Maria Fernanda Elsevier (2015)The dissolution of a zirconium white frit has been studied in order to know the kinetics of the process. The concentrations of five cations (Ca, Mg, Zn, Si and B) have been determined by ICP-OES after carrying out the ... -
Relationship between certain ceramic roofing tile characteristics and biodeterioration
Gazulla Barreda, Maria Fernanda; Sánchez-Vilches, Enrique; González, J. M.; Portillo, M. C.; Orduña, Mónica Elsevier (2011)This paper examines the relationship of certain red ceramic roofing tile properties to roofing tile biodeterioration. The following properties were studied: apparent porosity, roughness, and the presence or absence of two ... -
