CONCRE-SET – Concrete Set Accelerator is a chloride-free liquid admixture concentrate
formulated to accelerate concrete setting and improve early trowelling
and early-strength development, particularly in cold weather. Recommended for professional use only.
Suitable for general concrete, reinforced concrete, precast concrete,
concrete repairs and cold-weather applications where faster setting is
required.
Benefits
- Accelerates initial and final set
- Improves early-strength development
- Reduces waiting time before finishing
- Assists earlier formwork removal
- Suitable for cold-weather concreting
- Chloride-free formulation, reducing risk of rusting / corrosion to reo bars and concrete cancer
- Ready-to-use liquid
Directions for Use
Recommended Dosage
Typical dosage is
2–5 litres per cubic metre of
concrete.
For faster setting, cold weather or rapid-turnaround applications,
dosage may be increased up to
10 litres per cubic metre of concrete.
For applications previously using standard calcium nitrate 50%
solution, commence trials at approximately half the previous dosage.
Example: Where 20 litres of calcium nitrate 50%
solution was previously used, commence trials with 10 litres of
CONCRE-SET.
The optimum dosage will vary depending on concrete temperature, cement
type, concrete mix design, batch size and the required setting time.
A trial batch using the actual concrete mix is recommended before
full-scale use.
Method of Addition
- Add directly into the concrete mixer or agitator after the batch
water has been introduced.
- Do not add directly onto dry cement.
- Mix thoroughly for at least 2 minutes after addition to ensure
uniform distribution throughout the concrete.
- Where other admixtures are used, add each product separately unless
compatibility has been confirmed.
Important
Excessive dosage may result in:
- Rapid slump loss
- Reduced placing and finishing time
- Excessively rapid setting
- Variable concrete performance
Do not exceed the recommended dosage without prior testing. Concrete
performance may vary with temperature, cement source, aggregate, water
content and other admixtures.
Storage
Store in the original sealed container in a cool, dry and
well-ventilated area. Protect from contamination, direct sunlight and
extreme temperatures.
Recommended storage temperature: 5°C to 45°C
If crystallisation occurs during cold storage, warm the product gently
and mix thoroughly before use.
Shelf Life
12 months from the date of manufacture when stored correctly in the
original sealed container.
Safety
Refer to the Safety Data Sheet before use. Wear appropriate personal
protective equipment, avoid contact with skin and eyes, and keep out of
reach of children.
Use Recommendations
Refer Label, TDS or SDS
