Experimental assessment of swelling potential in montmorillonite soils
(Journal of Physics: Conference Series, 2021-06-09)
The study of the physicochemical activity of clays is essential to understand the
mechanical-hydraulic behavior. The experimental analysis of the expansivity of soils is linked
to the content of clay minerals present in ...
Novel method for stress history analysis in normally consolidated clays
(Journal of Physics: Conference Series, 2021-06-09)
The historical investigation of stresses in a clay material is essential to predict the
compressible behaviour of a soil layer that, in most cases functions as a foundation support of
superstructures. Because the stresses ...
Predictive model of mass flows of gaseous emissions from beehive ovens
(Journal of Physics: Conference Series, 2021-08-09)
One of the techniques used in the industry for the control of variables is, from their
magnitudes, such as fuel flow, air volume, amount of material mass, among others. The ceramic
industry needs to measure and control ...
