A concrete antifreeze or hydration accelerator is a great and cost-effective use when concreting in cold weather. Concrete antifreeze is actually a kind of premixed concrete based additive on nitrogen-free chloride material, so its applications can be described in reinforced and non-reinforced concrete.
Necessity of application and benefits:
- Concreting in cold and frosty weather up to -15 ° C and preventing concrete frost
- Initiation of hydration at temperatures below + 5 ° C
- Faster grouting of concrete and mortar
- Increased hydration and temperature of concrete
- Provide earlier primary resistance
- Reduce the freezing point of mixing water by increasing the heat of concrete and mortar
- Reduce the ratio of water to cement per constant efficiency
- Improve the durability of concrete against cold
