MasterFlux 80RMX

High Strength Non-Shrink Ready-Mix Grout (formerly BluCem RMX HS80)

How Does MasterFlux 80RMX Work?

MasterFlux 80RMX is a ready-mix, high-strength cementitious grout delivered pre-mixed in concrete agitators for on-site application. It is a highly fluid, volumetrically stable, Class C grout with early and long-term shrinkage-compensating additives. These properties make it ideal for critical applications, preventing shrinkage cracking or settlement.

Recommended Uses:

• Structural grouting – provides high-strength support for structural elements.

• Pile jacket grouting – ensures durable and stable encasement of piles.

• Annulus grouting – fills voids efficiently, preventing settlement and shrinkage.

What Are the Unique Features of MasterFlux 80RMX?

MasterFlux 80RMX  is specifically formulated to compensate for expansion in both the plastic and drying stages, ensuring durability and stability.

What Are the Benefits MasterFlux 80RMX?

• High strength – achieves compressive strengths greater than 70 MPa.

• Highly fluid – ensures easy placement with a slump/flow of >650mm.

• Volumetrically stable – Class C grout with early and long-term shrinkage compensation.

• Non-shrink – compliant with ASTM C1090, preventing shrinkage cracking or settlement.

• Zero bleed – prevents segregation and ensures uniform performance.

• Fine particle size – Maximum particle size of 1mm for smooth, consistent application.

• Time-efficient – reduces construction timelines with quick and continuous placement.

• Durability – engineered to compensate for expansion in both plastic and drying stages.
