Purity: Industrial Grade ≥99%
Appearance: Colorless to pale yellow viscous liquid
Solubility: Soluble in water, ethanol; slightly alkaline

Early Strength Agent
Accelerate cement hydration, improve 1d / 3d / 7d strength significantly.
Suitable for precast concrete, winter construction, quick formwork removal.
Water-reducing & Plasticizing Agent
Improve workability, slump retention and pumpability.
Synergize with polycarboxylate ether (PCE) or naphthalene superplasticizer.
Cement Grinding Aid
Reduce grinding energy consumption, increase cement fineness and strength.
Corrosion Inhibition Auxiliary
Improve concrete density and impermeability; help protect rebar from corrosion.
Dosage
General dosage: 0.02% – 0.05% by weight of cementitious materials
Optimum dosage: 0.04%
Max limit: ≤ 0.10% (overdose may cause retardation or strength loss)
Features & Advantages
