Bentonite concentration and storage time determine the rheological properties. A significant yield value is required to break particle network with storage time. The pH of acidic suspensions changes to neutral or basic with storage time.
Natural calcium bentonites have a neutral pH (level around 6.5 to 8.5) whereas activated calcium bentonites have a much more alkaline pH (level around 8.5 to 10.0). Natural sodium …
The effect of pH on the rheological behavior of three purified sodium bentonite (HP, GP, and WP) suspensions is studied. Each clay is studied as a function of pH, at a …
pH: Bentonite has a pH between 8 and 10, making it alkaline. Chemical formula: The chemical formula for montmorillonite, the primary mineral in bentonite, is (Na,Ca)0.33(Al,Mg)2Si4O10(OH)2•nH2O.
The pH of aqueous bentonite suspensions is known to be influenced by carbonates present even in minor amounts. On the other hand, at high solid:liquid ratios (at standard pH …

Four different chemical conditions are tested to investigate the influence of pH and type of monovalent electrolyte on the local rheological behavior of bentonite suspensions.
The typical pH of Ca-bentonite suspension ranges from 7 to 8 in contrast to Na-bentonite with pH values ranging from 9 to 10 (Kaufhold, Doann, Koch, & Houben, 2008). …
pH values of aqueous bentonite suspensions. Key Words—Bentonite pH, Carbonate Content, Clay-water Interaction INTRODUCTION The 'pH' of soils and clays is commonly determined …
The pH level of bentonite slurry plays a significant role in borehole soil stabilisation. From the "pH" value we can understand if the slurry is acidic or alkaline. A pH of around 7.0 is considered neutral, lower than 7.0 is acidic, …
