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 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 .
Montmorillonite is a dioctahedral 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.
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. The property of swelling also makes sodium bentonite useful as a sealant, since it provides a selfsealing, low ...

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 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.
available, synthetic bentonite can be prepared from fuller''s earth,, calcium bentonite, by treating it with anhydrous soda ash. USES SPECIFICATIONS Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well
Rs 1, / Metric Ton (Approx). Use : Animal Feed, Cattle Feeds Sodium bentonite is a highly swelling natural clay, available as a fine powder form. Sodium bentonite is used in stock feed for its benefits of high water absorption, cation exchange ability and organic absorption properties. Fine bentonite is useful as a binder in pelleted feeds more...

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.
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.
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.
The Company has extensive reserves of high quality Sodium and Calcium Bentonite which are mined processed carefully into several grades. These are in different forms such as dried crushed lumps, granules, powder to micronized powder, catering to diverse needs of clients. Our Bentonite products cater to a wide range of industries starting ...
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 ...
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.
Sodium bentonite expands when wet, absorbing several times its dry mass in water. As with Calcium bentonite, Sodium bentonite is widely used in the health and beauty industry in cosmetics and as a detoxification agent. Bentonite clay carries a strong negative charge which .
