CSA Cement

CSA cement introduction

CSA cement is a special cement used in many applications where early high strength and fast setting development are necessary. CSA cement is short for Calcium Sulfoaluminate Cement, also named rapid setting cement, high strength cement, fast hardening cement, CSA type III and CSA binder.

CSA cement Characteristics

• Appearance: light grey powder
• Early-high strength
• Rapid setting: initial setting time can reach 12~20 minutes
• Tiny expansion and low shrinkage
• Low degree of shrinkage
• Low alkali: PH value is about 11 and lower than Portland cement.
• No rust to steel
• Freeze-thaw resistance
• Impermeability
• Resistance to sulfate attack
• Low carbon footprint
