Calcium Aluminate Cement from United States
Calcium aluminate cement is a hydraulic binder produced from limestone and bauxite, known for its high early strength and resistance to chemical attack. It sets and hardens through hydration reactions, making it suitable for refractory and rapid-repair applications. This product falls under tariff item 2523.90.00 as an 'other hydraulic cement' because it is not classified as Portland, aluminous, slag, or supersulphate cement under the preceding specific headings.
