Expansive Hydraulic Cement from Germany
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.

Import Tips
• Provide technical data sheets to demonstrate the cement's expansive properties and distinguish it from standard Portland cement
• Ensure the product is not mixed with other materials that could change its classification
• Verify that any additives do not render the cement particularly suitable for specific use beyond general construction
