Calcium Sulfate (Plaster, Gypsum and Anhydrite)

In its Plaster, Gypsum, and Anhydrous forms, Calcium Sulfate is used in various types of concrete mortar, self-leveling compounds, tile adhesives, and fast-setting dry-mix systems. The specific type and amount of plaster, gypsum, or Anhydrite used will depend on the particular properties required for the product. For example, some formulations may require higher strength or faster setting time, while others may require increased flexibility or water resistance.

Here are some examples of Calcium Sulfate applications:

• Plaster, Gypsum, and Anhydrite can be binders in concrete mortar. When mixed with sand and water, they create a paste that can fill gaps or joints in a masonry or concrete surfaces. The resulting mortar can be used for bricklaying, tiling, and renders (stucco) applications.
• Gypsum and Anhydrite can be used in self-leveling compounds when mixed with water and other additives to create systems with high flow and fast drying. They are used to level uneven concrete surfaces or prepare floors to install flooring materials.
• Tile adhesives can create a paste that adheres tiles to various surfaces if mixed with other materials such as sand and polymers, Plaster, Gypsum, and Anhydrite. These adhesives can be used for both interior and exterior tile installations.
• For fast-setting Dry-mix systems, Anhydrite is often a key ingredient. When mixed with other materials such as Portland and specialty cement like CSA or CAC cement, sand, and additives, it creates a fast-setting compound that can be used for various applications, including repairing concrete surfaces and setting posts or poles.
