Grey Sulfoaluminate Cement 42.5 – High Early Strength CSA Binder for Mortar & Grouting

Short Description:

Yinshan Grey Sulfoaluminate Cement (CSA Cement) is a high-performance hydraulic binder with rapid hardening, high early strength and micro-expansion properties. It is manufactured from anhydrous calcium sulfoaluminate and dicalcium silicate clinker, combined with limestone and gypsum.

Key Features

• High Early Strength: Achieves 30MPa within 6 hours, enabling rapid demolding and shorter production cycles.
• Micro-Expansion: Free expansion rate of 0–0.06%, effectively compensating for shrinkage and preventing cracks.
• Excellent Durability: Dense structure provides 2–3× higher impermeability than OPC; freeze-thaw resistance up to 300 cycles.
• Corrosion Resistance: Superior resistance to seawater and sulfate corrosion (corrosion coefficient >1).
• Low Alkalinity: pH ≤10.3, reducing alkali-aggregate reaction risk.

Main Applications

• Self-leveling mortar – fast setting, excellent fluidity for seamless flooring
• Repair mortar – quick repairs for pavements, bridges and building structures
• Grouting materials – equipment foundation grouting, pile sealing and anchoring
• Waterproof materials – plugging agents and expansion joint fillers
• Precast components – accelerates demolding and turnover efficiency
