MasterPolyheed 8191

New Generation Robust PCE-Based Water Reducing and Set-Retarding Admixture

How Does MasterPolyheed 8191 Work?

MasterPolyheed 8191 is a robust and economical water-reducing and set-retarding admixture based on a specially formulated modification of the latest polycarboxylate ether chemistry from Master Builders Solutions. The product has been primarily developed for all types of normal and specialty concrete classes in the premix, precast, and in-situ concrete within the target slumps up to 120 mm, providing workable and cohesive mixes with less water.​

Recommended Uses:

• All types of concrete where a non-chloride water-reducing admixture is required, e.g., foundations, slabs, driveways, floor slabs, etc.

• Applications where good rheology, easier screening, and finishing are required for pumped and conventionally placed concrete

• A combination of water reduction and workability in concrete mixes

What Makes MasterPolyheed 8191 a Unique Solution?

MasterPolyheed 8191 has been specifically developed to enhance overall optimum performance in terms of water reduction, slump retention, compressive strengths, and superior mix rheology while maintaining control of the extension of set retardation under high-temperature conditions. MasterPolyheed 8191 is ideally “robust” in lean concrete mixes and in concrete that uses manufactured sand and recycled materials.

What Are the Benefits of MasterPolyheed 8191?

• Efficient dispersion of binders in ordinary concrete mixes

• Improved workability retention at higher temperatures

• Improved pump operating pressures

• Greater cohesion control of lean mixes

• Normal setting characteristics under cool conditions (i.e., winter in combination with accelerators) allow earlier finishing of slabs

• Reduced water content for a given workability
