CSA Binder Introduction:
Calcium Sulfoaluminate binder is pure CSA clinker that grinded without any gypsum. It is a hydraulic cementitious material blend high in C4A3S (Calcium Sulfoaluminate Crystals).
CSA Binder characteristics
• Appearance: light grey powder
• Rapid strength development
• Rapid setting: initial setting time can reach 12~20 minutes
• Shrinkage compensation
• Short Curing phase
• Low alkali
• Freeze-thaw resistance
• Impermeability
• Resistance to sulfate attack
• Low carbon footprint
