Bentonites are colloidal and plastic clay materials composed largely of montmorillonite (a species of dioctedral smectite). The properties of bentonites can vary considerably depending on geological origin and any postextraction modification, and their individual characteristics have a marked bearing on their economic use. Bentonites (E558) are currently authorised for use as feed additives ...

One method of controlling the origin of leaks is to use plastic concrete cutoff walls. Bentonite is one of the most important materials used in constructing plastic concrete which act as a stabilizing agent. It is from clay materials having high water absorption and swelling of 300% properties even after contacting with water. These properties may cause negative effects on plastic concretes ...

The applicant proposes to use bentonite at the maximum level of 20,000 mg/kg complete feed. The additive apparently interferes with the analysis of aflatoxin B1 in feed. The safety of the additive was already evaluated by the Panel in an opinion delivered in 2012. Bentonites are safe for all animal species, the consumers and the environment when used at a maximum level of 20,000 mg/kg .

The use of up to 5% is common, especially where high plasticity is needed it a white burning body. High amounts of bentonite will dramatically slow down the drying rate. In certain applications it is practical to use bentonite as the only plasticizer in a mix ( % with Redart to make a terra cotta).

Bentonite is a very plastic clay that shrinks (or swells) markedly in response to the removal (or addition) of water. There are three main types of bentonite: high swelling (sodium) low swelling (calcium) moderate swelling (intermediate sodiumcalcium) bentonite. The sodium bentonites are the most useful because of their greater swelling capacity. They are used mainly as bonding clay in ...
