Calcium Sulphate B-Anhydrite in CSA Cement Systems
Understanding Sulfate Source and Binder Balance in CSA-Based Mortar Formulation
Calcium Sulphate B-Anhydrite can be used as a sulfate source and binder balance component in CSA-based mortar and floor screed systems.
Role of B-Anhydrite
In CSA-based systems, the sulfate source can influence reaction behavior, setting direction, ettringite formation and dimensional stability. Calcium Sulphate B-Anhydrite is one possible calcium sulphate source for formulation discussion.
It is commonly considered in self-leveling screeds, pumpable floor screeds and CSA-based dry mix mortar systems. Final performance depends on binder balance, raw materials and testing.
Key Points
Sulfate source
Can provide calcium sulphate direction for CSA-based binder balance.
Setting influence
Sulfate balance may affect setting behavior and early reaction.
Flooring systems
Often discussed for self-leveling and pumpable screed applications.
Compatibility
Must be checked with CSA Binder, CSA Cement, cement and additives.
Flow and surface quality
Flooring applications require flow, leveling and surface testing.
Trial mix required
Dosage and binder balance should be verified by testing.
Formulation and Application Notes
- Do not treat one sulfate source or dosage as universal for all CSA systems.
- Check compatibility with water reducer, defoamer, retarder and polymer additives.
- Evaluate flow retention, setting, surface quality and strength direction together.
- Confirm latest TDS and local test method before commercial use.
