MasterPolyheed 8195

New Generation Mid-Range Water Reducer with Suretec (Super Retention Technology)

How Does MasterPolyheed 8195 Work?

MasterPolyheed 8195 is a non-chloride, robust, specially formulated polycarboxylate ether-based mid-range water-reducing admixture (MWR). It has been developed for all types of premix, precast, and in-situ concrete (including post-tensioned applications) and contributes significantly to improving the fresh and hardened properties of concrete. MasterPolyheed 8195 meets the requirements for mid-range water-reducing admixtures according to AS 1478.1-2000, Type MWR.

Recommended Uses:

• All types of concrete (25 – 50 MPa) in the mid-range workability band (100 - 150mm slump) requiring workability retention (~ 60 – 120 min) without excessive retardation

• Precast concrete

• Post-tensioned concrete applications

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

• “Green” concrete mixes with high % of SCM’s

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

What Makes MasterPolyheed 8195 a Unique Solution?

MasterPolyheed 8195 is a versatile admixture able to produce and maintain mid-range slumps for extended periods without retardation. Its unique formulation can improve the rheology and finishability of concrete.

What Are the Benefits of MasterPolyheed 8195?

• Normal setting characteristics throughout the recommended dose range

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

• Superior slump retention

• Improved workability and pumpability

• Reduced water content for a given workability

• Enhanced finishability improving finished appearance

• No added chlorides, thus conforming to the most stringent chloride ion limits including AS3600

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

• Increased durability (e.g. permeability, water-tightness)

• Reduced cracking

• Neutral effect on drying shrinkage
