Thermodynamics of Clay Minerals

ThermoChimie database developments in the framework of cement/clay interactions

“…A compilation of the measured thermodynamic properties is provided in Table 1. Model developments have been published by Vieillard et al (2011) and Blanc et al (2013Blanc et al ( , 2014b and the introduction of theoretical clay mineral end members in the thermodynamic database has been described by Blanc et al (2014b). The results from solution experiments were reported by Gailhanou (2005) Gaucher et al, 2004b).…”

“…For clay minerals, the database was provided with a selection of kinetic parameters proposed by Marty et al (in press), for the TST (Transition State Theory) rate law. Considerations about equilibrium attainment have been discussed by Blanc et al (2013). For example, two years appears to be the minimum duration for clay minerals to reach thermodynamic equilibrium, at least at room temperature.…”

Application of Optimization Technology During Performance Petrophysical Researches

“…Practacal laboratory studies show that the clay content of the samples can be determined by conducting grain-size analysis of core material [11,12] and studying the total mineral composition of rocks by the method of X-ray phase analysis [13,14].…”

“…Depending on the sample preparation of drugs, the dynamics of changes in the type of diffraction patterns are studied. It makes it possible to identify the mineral composition of rocks and use the service programs to quantify the content of various types of minerals in the sample [13,14].…”

Comportamiento térmico y mecánico del yeso con adiciones de aerogel de sílice granulado

“…El análisis termogravimétrico se utiliza habitualmente para calcular el agua molecular de los sulfatos de calcio, con el fin de cuantificar las fases; no obstante, en la presente tesis, ese tipo de cuantificación no pudo llevarse a cabo debido al contenido de agua interlaminar en los filosilicatos, que conlleva una pérdida de peso en rangos de entre temperatura ambiente hasta los 250 °C, de acuerdo con Warne y Blanc et al, solapándose a los de los sulfatos de calcio hidratados y semihidratados, por lo que esta técnica no se utilizó para este fin [Blanc et al, 2013;Warne, 1978].…”
