MasterFlux EA 55RMX

Low Thermal Resistivity Ready Mix Grout (formerly BluCem RMX EA55)

How Does MasterFlux EA 55RMX Work?

MasterFlux EA 55RMX is a one-component powder additive designed for use in a specified mix at an approved batch plant to produce a highly fluid, heat-dissipating cable grout. It is specifically formulated for deep-pour applications, effectively dissipating heat from high-voltage cables through conduit encasement.

Recommended Uses:

MasterFlux EA 55RMX is designed for applications that require heat dissipation and high fluidity. Its key areas of application include:

• High-voltage cable grouting – used in conduit encasement to dissipate heat from power cables.

• Deep pour grouting – suitable for large-volume placements where low heat generation is required.

• Bulk grouting – ideal for ready-mix applications that demand controlled thermal properties.

• Long-distance pumping – its high fluidity allows for efficient placement over extended distances.

• Infrastructure protection – used in environments where low exothermic heat helps prevent damage to surrounding services.

• Thermally conductive applications – ensures effective heat transfer in power transmission and industrial settings.

What Are the Unique Features of MasterFlux EA 55RMX?

With its pumpable consistency, MasterFlux EA 55RMX is well-suited for long-distance and bulk grouting where heat management is critical. By incorporating slower-reacting cements and thermally conductive additives, it generates low exothermic heat during mixing, allowing for controlled placement in large pours while maintaining thermal stability. This ensures efficient heat transmission throughout its service life, protecting surrounding infrastructure and minimising thermal shrinkage.
