Effect of thermal treatment on pozzolanic activity of excavated waste clays
(Elsevier, 2019-06-30)
Samples of excavated waste clays were characterized by X-ray fluorescence, laser granulometry, specific surface area, X-ray diffraction, and thermo-gravimetric analysis. Excavated clays were calcined at 550 ºC and 650 ºC ...
Preparation and characterization of natural rubber/organophilic clay nanocomposites
(John Wiley and SonsHoboken, 2015)
Natural rubber/organophilic clay ananocomposites were prepared and characterized. A brown bentonite from Paraiba's State Btazil waste modified with a sodium salt and treated with quaternary ammonium salt hexadecyltrimethyl ...
Selective sorption of mercury(II) from aqueous solution with an organically modified clay and its electroanalytical application
(Taylor & Francis Inc, 2006-01-01)
The organo-clay used in this work was prepared from a Na-montmorillonite (Wyoming-USA deposit) by treatment with water solution of hexadecyltrimethylammonium cations. As organo-clays exhibit strong sorptive capabilities ...
Using the mineralogy of river sediments as pollution indicator of clay mining activity
(Assoc Brasileira Recursos Hidricos-abrh, 2016-07-01)
View of the difficulty to elect standards for water pollution control in clay mining activity, this study aimed to verify the possibility of using the mineralogy of river sediments as a pollution indicator of clay mining ...

Effects of adding nano-clay (montmorillonite) on performance of polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives in Carapa guianensis, a tropical species
(Elsevier Ltd, 2015-06)
The aim of this study was to improve the bond strength resistance of polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives modified with nano-clay (montmorillonite) with a tropical species of wood known to exhibit ...
A method for total analysis of minor and trace elements in the soil clay fraction to atmospheric aerosols.
(Sociedad Chilena de Química, 1984)
Several methods recommended for soil analysis using acid digestion were tested for the total analysis of minor and trace elements of the clay fraction. The proposed method using mixtures of HClO4/HF was adequate to dissolve ...
