MasterRoc ACP 212

​​MasterRoc ACP 212

Water-soluble anti-clay soil conditioning polymer for Tunnel Boring Machines (TBM)

​How does MasterRoc ACP 212 work?

MasterRoc ACP 212 is a liquid anti-clay polymer specially designed for use with highly cohesive and adhesive soils (such as marl, silts, and clays that contain fine particles). MasterRoc ACP 212 anticlay polymer can reduce or eliminate the stickiness and adhesiveness of the clay, allowing easy transport of muck, and reducing the risk of blockage at the cutterhead and in the excavation chamber under conditions of high pressure and high temperature.

What are the unique features of MasterRoc ACP 212?

• Creates plastic deformation properties in the soil

• Lowers inner friction and abrasiveness of the soil at the cutterhead

• Reduces clogging and adhesion on the cutterhead and the screw conveyor

• Reduces cutterhead torque

• Prevents the re-agglomeration of clay from chips to blocks

• Excellent ability to disperse insoluble inorganic salts and soil particles

What are the benefits of MasterRoc ACP 212?​

• Reduces risk of surface settlement

• Reduces soil blockage and promotes easy mucking

• Increases TBM advancement speed
