Ground Calcium Carbonate (GCC) is often used as an additive alongside bentonite to improve its performance in various industrial applications. When combined with bentonite, GCC enhances the mixture’s flowability, consistency, and moisture retention. This combination is particularly useful in drilling fluids, foundry molds, and sealing products, where improved rheological properties and stability are essential. GCC also helps reduce costs by partially replacing more expensive components while maintaining the desired physical and chemical characteristics. Together, GCC and bentonite create more efficient, durable, and cost-effective solutions across multiple industries.
