Mar 08, 2018· Bentonite is very unusual in the fact that once it becomes hydrated, the electrical and molecular components of the clay rapidly change and produce an 'electrical charge'. When it becomes mixed with water it rapidly swells open like a highly porous sponge.
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite.It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al).

Bentonite also contains beidelite (montomorillonite family) as principal mineral. Bentonite is mixed with sand to impart plasticity and strength to it in the presence of moisture. The fine particle size and high moisture absorption, that is, high swelling property of bentonite give bonding strength or adhesion to the mass of sand grains.
