Calcium Aluminate Cement
Calcium aluminate cement is a hydraulic binder made from limestone and bauxite, offering high early strength and resistance to chemical attack. It sets and hardens through hydration reactions, distinct from Portland cement, and is used in refractory and rapid-repair applications. This product falls under tariff item 2523.90.00 as 'other hydraulic cements' because it is not a Portland, aluminous, slag, or supersulphate cement.
Colored Hydraulic Lime Cement
Colored hydraulic lime cement is a hydraulic binder mixed with iron oxide pigments for aesthetic restoration projects. It sets through hydration of free lime and other compounds, providing a durable, breathable material. This product is classified under 2523.90.00 as 'other hydraulic cements' because it is not a standard Portland or aluminous cement, and the added pigments do not exclude it from Chapter 25.
Expansive Hydraulic Cement
Expansive hydraulic cement is formulated with ettringite-forming agents to compensate for shrinkage in concrete, ensuring crack control in prestressed structures. It hardens through hydration, similar to other hydraulic cements, but has unique expansive properties. This product is classified under 2523.90.00 as 'other hydraulic cements' because it does not fit the definitions of Portland, aluminous, slag, or supersulphate cements.
High Alumina Cement
High alumina cement is a hydraulic binder made from bauxite and limestone, known for rapid hardening and high-temperature resistance. It sets and hardens in air or underwater through hydration of calcium aluminates. This product is classified under 2523.90.00 as 'other hydraulic cements' because it is not a Portland cement, and while it is aluminous, it is not specifically classified under the aluminous cement subheading if it does not meet the exact definition.
Masonry Hydraulic Cement
Masonry hydraulic cement is a blend of natural cement and limestone, designed for tuckpointing and restoration work, setting hydraulically. It provides a durable, breathable mortar that matches historic structures. This product is classified under 2523.90.00 as 'other hydraulic cements' because it is not a standard Portland cement and has unique properties for masonry applications.
Natural Cement Clinker Ground
Ground natural cement is produced from argillaceous limestone kilns, providing hydraulic setting similar to Roman concrete. It is used in sustainable historic restoration projects. This product is classified under 2523.90.00 as 'other hydraulic cements' because it is a natural hydraulic cement, distinct from synthetic Portland cement.
