Triethanolamine Concrete Admixture Tank Selection

Storing Triethanolamine Concrete Admixture? Start Here

Triethanolamine (TEA) is a versatile ingredient used in concrete production, primarily as a grinding aid, set-time accelerator, and corrosion inhibitor. It's a clear-to-pale-yellow liquid that plays a crucial role in improving cement strength and protecting steel in concrete. Whether you're operating a cement mill, admixture plant, or ready-mix facility, understanding how to store TEA properly is essential for maintaining its effectiveness and ensuring safety.

Can you store it in a poly tank?

Yes, you can store triethanolamine in a polyethylene (poly) tank. Both HDPE and XLPE tanks are standard for atmospheric storage of TEA at industrial sites. These materials handle the mildly alkaline nature of TEA well, making them suitable for bulk storage.

Key Issue: Temperature Sensitivity

TEA is quite viscous, especially at lower temperatures. This means that in colder environments, managing the viscosity is crucial to ensure smooth pumping and mixing. Consider heat tracing or insulation for your storage setup if you're in a region with cold weather.

The safety that actually matters

• Use HDPE or XLPE tanks for safe storage.
• Avoid aluminum, galvanized steel, brass, and bronze fittings as they can react with TEA.
• Ensure proper temperature management to handle viscosity changes.

Common questions

What type of gaskets should I use?

EPDM and Viton gaskets are recommended for TEA storage.

Can I use a metal tank for TEA?

304L and 316L stainless steel are acceptable, but avoid aluminum and galvanized steel.

How do I manage TEA's viscosity in cold weather?

Consider using heat tracing or insulation to maintain a manageable viscosity.
