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