An anti-freeze built on formates (sodium/calcium formate) compounded with early-strength and water-reducing components — lowers the liquid freezing point and promotes low-temperature hydration for placement and strength gain in negative temperatures.
Lowers freezing point · Early-strength synergy · Workable at -15℃

- Recommended dosage
- 3.0% – 6.0% by binder weight (by ambient temperature)
Overview
This anti-freeze centres on formates compounded with early-strength and water-reducing components. It lowers the mixing-water freezing point and promotes cement hydration at negative temperatures, so concrete can set and gain strength around -15℃ per winter-concreting requirements.
Key benefits
- Markedly lowers liquid freezing point, widening the workable temperature window
- Early-strength synergy for strength gain in negatives
- Chloride-free or low-chloride — less rebar-corrosion risk
- Also water-reducing, better cold-weather workability
Usage
Dosage rises with forecast low temperature; pair with thermal storage and insulation curing. Prevent repeated freeze-thaw in the early age; follow JGJ/T 104 winter-concreting code for mix and curing.
Typical use
Winter concreting, northern infrastructure, low-temperature placement and early-strength-demanding concrete.

Product Q&A
What is the recommended dosage of Anti-Freeze Admixture (Formate Compound)?
Recommended dosage is 3.0% – 6.0% by binder weight (by ambient temperature). Run a small cement-compatibility trial first; we provide dosage guidance with every sample.
In which form is Anti-Freeze Admixture (Formate Compound) available?
Standard supply is Liquid. Other solid contents and packaging sizes can be made to order.
What is the MOQ and lead time for Anti-Freeze Admixture (Formate Compound)?
MOQ is 1 × 20'FCL (~20–24 t); lead time for stock grades is Stock grades 7–10 days. COA and MSDS are issued with every batch.
Can I get a free sample before ordering?
Yes. We send free samples up to 2 kg per grade with COA, plus a recommendation matched to your cement and application.
How should I store it and what is the shelf life?
Store sealed, away from light, at 5–35℃: 12 months (5–35℃, sealed, away from light). Reseal promptly after opening.
