MasterPolyheed 8820

New Generation, Normal to Mid-Range Water Reducer with Superior Slump Retention, Pumping, and Finishing

How Does MasterPolyheed 8820 Work?

MasterPolyheed 8820 is a multi-component, non-chloride, normal to mid-range water-reducing admixture designed to improve the performance of concrete both in the plastic and hardened states. It is added to the initial batch of water at the batching plant.

Recommended Uses:

• All types of concrete where a non-chloride water-reducing admixture is required, especially in the normal to mid-range slump band

• Improving the performance of pumped concrete, shotcrete, and conventionally placed concrete

• Improving the performance of plain, reinforced, precast, lightweight, or standard-weight concrete

• Use in white or coloured concrete

• Use in architectural concrete, especially where off-form and/or surface finish is critical

• Use in concrete containing harsh aggregates and/or manufactured sand

What Makes MasterPolyheed 8820 a Unique Solution?

MasterPolyheed 8820 is a versatile admixture able to produce and maintain mid-range slumps for extended periods without retardation. Its formulation contains materials able to improve the concrete’s workability and finishability.

What Are the Benefits of MasterPolyheed 8820?

In the Plastic State:

• Normal setting characteristics throughout the recommended dose range

• Reduced segregation, particularly in lean mixes and mid-slump concrete

• Superior slump retention

• Improved workability

• Improved pumpability

• Reduced water content for a given workability

• Enhanced finishability

In the Hardened Concrete:

• No added chlorides, conforms to the most stringent chloride ion limits including AS3600 concrete structures code, will not initiate or promote the corrosion of reinforcing steel

• Increased strength – compressive, flexural, and bond (concrete to steel)

• Superior finished appearance

• Increased density and durability

• Reduced permeability – improved water tightness

• Reduced cracking

• Reduced shrinkage and creep
