MasterPolyheed 8830

New Generation Mid-Range Water-Reducing Admixture for Improved Concrete Performance

How Does MasterPolyheed 8830 Work?

MasterPolyheed 8830 is a multi-component, non-chloride, mid-range water-reducing admixture designed to improve the performance of concrete both in the plastic and hardened states. It is added at the batch plant after 75% of water has been added to the mix.

Recommended Uses:

• All types of concrete where a non-chloride water-reducing admixture is required, especially in the slump band (80–150 mm)

• 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 8830 a Unique Solution?

Non-chloride water-reducing admixture enables a mid-range concrete slump of 80–150 mm.

What Are the Benefits of MasterPolyheed 8830?

In the Plastic State:

• Normal setting characteristics throughout the recommended dose range

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

• Improved mix rheology

• Improved pumpability

• Reduced water content for a given workability

• Enhanced finishability, especially for concrete with manufactured or harsh aggregates

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
