MasterGlenium SKY 8455

Robust High-Range Water Reducing Admixture with Suretec for Premixed and Precast Applications

How Does MasterGlenium SKY 8455 Work?

MasterGlenium SKY 8455 is a uniquely formulated, latest-generation High-Range Water Reducer with super retention and fast wet-out technology. It contains polycarboxylate ether polymers combined with SURETEC polymers for ready-mixed and precast concrete where moderate slump retention, improved rheology, durability, and high early and ultimate strengths are required. The product is also designed for use with concrete ingredients that may be inconsistent in quality.

Recommended Uses:

• Premixed and precast concrete

• Faster dispersion resulting in time savings

• High flowing concrete

• Concrete requiring improved surface finish

• High-strength and ultra-high-strength concrete

• Super workable concrete, self-consolidating concrete, self-compacting concrete (SCC)

• High-performance concrete (HPC) with high durability specifications

• Pumped concrete

• Piling mixes

• Pre-stressed and post-tensioned concrete

What Makes MasterGlenium SKY 8455 a Unique Solution?

A unique combination of dispersion and steric hindrance effects makes the admixture ideal for the ready-mixed and precast concrete industries. MasterGlenium SKY 8455 enables the concrete producer to produce high-performance, high-strength, and self-compacting type mixes with relatively low and stable air contents.

What Are the Benefits of MasterGlenium SKY 8455?

• 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
