Z LIQUI-CRETE

ADMIXTURE

HIGHER-STRENGTH WITH REDUCED SET TIMES

 Z Liqui-Crete admixture converts White Portland Cement into a flowable, high performance, concrete benchtop mix.

The Z Liqui-Crete conversion kit is a multi-component admixture ideal for use in both cast-in-place and precast applications. Z Liqui-Crete contains a unique fibre that creates a bonded network reducing the likelihood of cracks forming. 

Each Z Liqui-Crete admixture is precisely measured for a consistent blend of cement, pozzolans, and other proprietary materials which will produce significantly higher strength and reduced set times over the standard concrete mix.

Composition:

Proprietary blend of cement, acrylic fibres, pozzolans, and rheology modifiers.

Compressive Strength (MPA)

@24 hours: 24

@ 7 days: 41

@30 days: 55

THE SIZE OF REINFORCING IN A BENCHTOP IS AN IMPORTANT CONSIDERATION

 

When concrete shrinks due to drying out, high tensile stress levels develop around proportionally oversized reinforcing. These stresses cause cracks that run along the length of the steel.

Smaller diameter reinforcing has less of an effect on the concrete, so the same amount of concrete shrinkage develops much less tensile forces, thus the likelihood of cracks caused by the steel itself drops dramatically.

 

All concrete shrinks to some degree and shrinkage occur over a long period of time, the occurrence of telegraph cracking may not appear until long after a countertop is installed.

Our recommendation is to use a fibreglass based composite mesh instead to prevent rust issues, ghosting and telegraph cracking.
