It is very critical to control curing of concrete in very low temperature in freezing cold weather & also to maintaining strength of cured concrete  in freeze-thaw cycle.

FROST-CUREX HD is a typical modern cold-weather accelerator admixture   formulation for reinforced concrete systems engineered with a blend of chemical accelerators, corrosion inhibitors, air-entraining agents, and shrinkage control components to provide a balanced performance under harsh cold conditions. In this formulation, the accelerator component (for cold weather) drives faster hydration so the concrete reaches critical early strength before temperatures drop below freezing. The shrinkage reducer reduces internal tensile stresses during drying and curing, which reduce cracking caused by thermal and moisture changes. The air-entraining component in FROST-CUREX  HD creates millions of tiny, stable micro-bubbles throughout the mix, which act as internal “pressure relief chambers” when water inside the concrete freezes and expands. This significantly improves resistance to freeze–thaw damage by relieving internal stresses due to ice formation. The corrosion-inhibitor component of formulation FROST-CUREX HD bonds concrete to steel reinforcement and reduces the ingress of aggressive ions, helping protect the steel from rust and prolong the life of structural bonds.

DOSE: 0.5% to 2.0 % of the dry cement depends upon the weather conditions,

APPLICATION:  The FROST-CUREX HD in desired ration is  diluted with   50% of  required water to make concrete mix and dilutant  added in concrete mixer.

ADVICE: Avoid overdose in use which may cause delay in setting /hydration time of concrete mix
