Bentonite is used as a material in the production of cement.It is added to cement to improve its performance in several ways. Here are someof the uses of bentonite in cement making:
Water retention: Bentonite can absorb large amounts ofwater, which helps to prevent the cement from drying out too quickly. Thisallows the cement to set properly and ensures that it is strong and durable.
Rheology control: The addition of bentonite can help tocontrol the flow of cement, making it easier to work with and improving the qualityof the finished product.
Cement stabilization: Bentonite can be used to stabilize thecement and prevent it from cracking or shrinking as it dries. This helps toensure that the finished product is strong and long-lasting.
Adhesion: Bentonite can improve the adhesion of cement toother materials, making it useful in applications such as mortar, grout, andconcrete.
The percentage ofbentonite used in cement making varies depending on the specific applicationand the desired properties of the finished product. Generally, the amount ofbentonite added to cement is relatively small, typically ranging from 1% to 10%by weight of cement.
