High Alumina Binders & Cements
High Alumina Binders and Cements are the critical bonding agents that transform individual refractory aggregates into a unified, high-strength monolithic structure. Based on calcium aluminate chemistry, these binders provide rapid strength development, exceptional refractoriness, and resistance to chemical attack at elevated temperatures. Imperial World Trade supplies a complete range of high alumina cement grades — from standard CA-25 and CA-50 to ultra-pure CA-70 and CA-80 — serving refractory manufacturers, ready-mix castable producers, and on-site lining contractors globally.
- CA-25 Grade: Cost-effective binder for general-purpose refractory castables up to 1,350°C.
- CA-50 Grade: The industry standard for dense and low cement castables; excellent balance of strength and refractoriness.
- CA-70 / CA-80 Grade: Ultra-low iron, high-purity binders for white castables and applications requiring superior chemical cleanliness up to 1,800°C.
- Rapid Strength Gain: Achieves handling strength within hours of casting, reducing installation downtime.
- Compatibility: Formulated for use with a wide range of tabular alumina, bauxite, and mullite aggregates.
- Consistent Fineness: Controlled particle size ensures uniform hydration and predictable setting behaviour.
Imperial World Trade supplies high alumina binders with full certificate of analysis for every batch, giving refractory formulators and end-users the confidence to engineer precise, repeatable lining performance.
