For the reader''s edification, we provide a very simplistic overview of the standard specification for using sodium bentonite in earth dam sealing which generally entails the following. Sodium bentonite can be thought of as a concentrated clay such that relatively small amounts blended with sandy soils drastically reduces permeability.
Sodium Bentonite Clay. 50lb. bag covers approx. 100 sq. ft. Sodium bentonite has proven to be one of the most effective sealants on the market. The fact that sodium bentonite swells many times its mass, then forms a strong water and chemical proof seal makes it .
Uses of Bentonite in Construction. The recognition of bentonite as a vital construction element is still in its latent stage, since a hefty percentage of foundations and other civil engineering activities are still carried out without using bentonite and are incurring much higher expenditure through use of .
Dry bentonite''s specific gravity is around Bentonites tend to break quickly into very small particles when in water dispersions. Wyoming Sodium bentonite provides 6065% particles smaller than, around 90% particles are finer than pm and around 97% will pass a 44 pm screen.
We test this Bentonite from each bed which is stockpiled to ensure that our products comply with set industry standards. These are then cautiously dried and ground to meet all the product specifications. Our bentonite minerals are extracted from deep mines .
Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. The different types of bentonite are each named after the respective dominant element, such as potassium(K), sodium (Na), calcium(Ca), and aluminium (Al). Experts debate a number of nomenclatorial problems with the classification of bentonite clays.

Three types of bentonite: 1) Natural Calcium Bentonite or Calcium Montmorillonite. 2) Natural Sodium Bentonite or Sodium Montmorillonite. 3) Sodium Activated Bentonites or Sodium Activated Montmorillonites. Bentonite minerals occur as lenses or seams containing up to 50% moisture.
CLAYTITE is a dual layer waterproofing consisting of HDPE (20 mil), sodium bentonite, and a protective layer consisting of a nonwoven polypropylene. The HDPE provides the first layer of waterproofing, while the bentonite''s selfsealing capabilities ensure positive puncture protection under hydrostatic conditions.
bentonite. Sodium bentonite is commonly distinguished by it''s ability to swell several times it''s natural volume when exposed to water. The test method used for quantifying the swelling property for use in GCLs is ASTM D5890 Standard Test Method for Swell Index of Clay Mineral Component of Geosynthetic Clay Liners.
Montmorillonite is a dioctedral layer silicate and in sodium form swells when mixed with water to form dispersed colloidsize particles. There are two common types of Bentonite for commercial use; sodium (or swelling) Bentonite and calcium Bentonite. Toxicology. Bentonite is nontoxic and inert.

Backed by a diligent team of professionals, we have been able to manufacture and supply a wide range of Sodium Bentonite Powder. Uses: Helpful in various geotechnical and environmental surveys Used for making different slurry walls Ideal for drilling mud for oil wells.
Sodium bentonite, with sodium cation prevalence (Na+) allows water to penetrate through the platelets, forcing them apart, thus leading to swelling. Conversely, calcium bentonite, with calcium cation prevalence (Ca2+), while getting hydrated in much the same way, due to its strong positive charge, has lower absorption properties, not permitting ...
Sodium Bentonite: Because of its high absorbency and clumping tendency, Sodium Bentonite is useful as a sealant. It is considered a safe, natural, nontoxic and inexpensive treatment for porous soils. Its swelling capacity gives Sodium Bentonite the ability to bond with soil .
Bentonite Wikipedia. Types Sodium bentonite. Sodium bentonite expands when wet, absorbing as much as several times its dry mass in water. Because of its excellent colloidal properties, it is often used in drilling mud for oil and gas wells and boreholes for geotechnical and environmental investigations.
Apr 18, 2020· API Bentonite API Bentonite is generally predominantly sodium bentonite; however, some degree of beneficiation is allowed under specifications for this material. The YP/PV ratio specification (3 maximum) limits this amount of beneficiation. Hence, API bentonite, under many conditions, performs similarly to the nontreated bentonite.
VERMONT CONSTRUCTION SPECIFICATION 11A – EARTHFILL – BENTONITE TREATMENT 1. Scope The work shall consist of base preparation, bentonite application, incorporating bentonite into soil and compaction of soil/bentonite liner. 2. Material A. Quality The bentonite supplied as a soil sealant shall be high swelling sodium montmorillonite clay.
Sodium Bentonite Source. Our bentonite clay is provided in granular form directly from the processing facility in Northeastern Wyoming. Bentonite Clay Application Rates for pond/lake bottoms. To properly apply bentonite to seal a pond, the pond must be drained and the bentonite clay then incorporated into the soil of the pond bottom and sides.
