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
