Evaluation of Egyptian bentonite and nano-bentonite as drilling mud [PDF]
Egyptian Journal of Petroleum, 2013 AbstractNano-particles of bentonite have been prepared by nano-grinding. The nano-bentonite was characterized by X-ray fluorescence analysis (XRF), X-ray powder diffraction (XRD), thermal gravimetric analysis (TGA) and Transmission electron microscopy (TEM). The bentonite particles had been ground to the size ranging from 4 to 9nm.

Calcium bentonite and sodium bentonite as stabilizers for roads unbound [PDF]
Cleaner Engineering and Technology, 2022 Several technologies are currently available to stabilize the unbound layers of road pavements. The use of these solutions, often manufactured by means of chemical processes, is steadily increasing worldwide. As an alternative natural resource, the use of bentonite represents a valid option when it comes to road stabilization and its application in ...
