    Evaluación del comportamiento de arcillas sometidas a diferentes tiempos de exposición a altas temperaturas
    (2013-11-15) Rondón-Quintana, Hugo Alexánder
    Laboratory tests were performed in order to evaluate the effects on the index properties, volumetric behavior and monotonic uniaxial strength of two clays caused by the application of different temperatures (150, 225 and 300 °C) for varying periods of time (1, 7 and 15 days). Additionally, we studied whether the clays recover the mentioned properties after being subjected to high temperatures and being again exposed to room temperature for one week in the laboratory. The mean objective of this research project is to evaluate whether the application of increasing temperatures in clays can be a good stabilization method in the future or if it is possible to produce mineral filler. Results show that the plasticity, expansion potential and monotonic uniaxial strength decrease when the temperature is raised up 150-300 °C on the samples and when the exposure time increased. Additionally, it is reported that the recovery of clay properties is zero when they are subjected to 300 °C for 15 days.
