MasterPozzolith 450

Non-Chloride Water Reducing Admixture

How Does MasterPozzolith 450 Work?

MasterPozzolith 450 is a ready to use liquid admixture formulated to improve the performance of concrete in both the plastic and hardened states. MasterPozzolith 450 is a non-retarding, water reducing, strength enhancing admixture which does not contain added chloride.

Recommended Uses:

• All types of concrete where a non-chloride water reducing admixture is required.

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

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

• Concrete subject to chloride ion constraints such as in coastal environments.

• Use in white or coloured concrete.

• Use in architectural concrete.

• Concrete placed on galvanised steel floor and roof systems which are left in place.

What Are the Benefits of MasterPozzolith 450?

In the plastic state:

• Superior finishing characteristics for slab work and off-form surfaces.

• Normal setting characteristics under cool conditions allowing earlier finishing of slabs.

• Reduced segregation particularly in lean mixes and high slump concrete.

• Improved workability.

• Improved pumpability.

• Reduced water content for a given workability.

• Compatibility with air entraining agents

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 watertightness.

• Reduced cracking.
