MasterRoc AGA 370

High-performance liquid accelerator as component B of two-components annular grout system for TBM tunneling

How does MasterRoc AGA 370 work?

MasterRoc AGA 370 is a high-performance liquid accelerator used during the injection of the two-components annular grouts behind the concrete lining of a Tunnel Boring Machine (TBM). MasterRoc AGA 370 is more commonly known as Component B of the annulus grout in TBM tunneling.

What is MasterRoc AGA 370 used for?

MasterRoc AGA 370 is designed for usage in two-component grouts where a rapid gel and early strength values are decisive. MasterRoc AGA 370 is fully compatible with retarders such as MasterRoc AGA 155 & MasterRoc AGA 255.

What are the benefits of MasterAir 760?

Operational

• Easily pumpable

• Fast setting and higher early strength achievement as compared with traditional accelerators

• Rapid work progress

• Easy workability and mixing in the grout

Technical

• Low viscosity

• Depending on dosage, MasterRoc AGA 370 ensures flexibility and control of gel time (setting time), and also on compressive strengths
