Silica Fume Slurry Concrete SCM Tank Selection

Storing Silica Fume Slurry? Start Here

Silica fume slurry is a key ingredient in high-performance concrete, especially for projects like bridge decks and parking garages. It's a byproduct of silicon and ferrosilicon production, and when mixed into concrete, it significantly enhances durability and strength. Most ready-mix plants prefer the slurry form because it's easier to handle and reduces dust. If you're storing this material, it's crucial to choose the right tank to ensure safe and effective storage.

Can you store it in a poly tank?

Yes, you can store silica fume slurry in a polyethylene (HDPE or XLPE) tank. These materials are standard for storing silica fume slurry due to their compatibility and durability. Polypropylene and PVDF are also suitable for fittings and pumps.

Key Issue: Abrasive Wear

Silica fume slurry contains tiny particles that can cause abrasive wear on pipes and pumps. To manage this, use abrasion-resistant materials like stainless steel or ceramic-lined piping for high-velocity transfers. Regular inspections and maintenance can help prevent wear and tear.

The safety that actually matters

• Use abrasion-resistant materials to reduce wear.
• Ensure proper sealing with EPDM or Viton gaskets.
• Regularly inspect tanks and piping for signs of damage.

Common questions

What type of tank is best for silica fume slurry?

HDPE or XLPE tanks are ideal due to their compatibility and durability.

How do I prevent abrasive wear?

Use abrasion-resistant materials like stainless steel or ceramic-lined pipes.

What gaskets should I use?

EPDM and Viton gaskets are recommended for their compatibility with silica fume slurry.
