About HS Code 252330
Aluminous cement, also known as calcium aluminate cement or Ciment Fondu, is a specialized hydraulic cement fundamentally different from Portland cement. It is characterized by its rapid hardening, high early strength, exceptional resistance to chemical attack (especially sulfates), and ability to withstand high temperatures. These unique properties make it indispensable for niche applications such as refractory concretes, sewerage systems, marine environments, and rapid-setting repair mortars. Trade in aluminous cement involves specialized manufacturers exporting to industries requiring these specific performance characteristics, often in smaller volumes than ordinary Portland cement. Strict quality control and specific application knowledge are crucial for its successful international distribution and use.
