WellFix FN is used in the process of well casing in winter conditions with the purpose of preventing freezing of cement mortars during their tempering and transportation. It also provides accelerated development of the initial strength of cement mortar under temperatures below 0°C. The WellFix FN additive improves rheological properties of cement slurry, thus, reducing the hydraulic resistance of cement mortar, and minimizing the pressure of pumping and squeezing when performing well cementing jobs.
Antifreeze agent WellFix FN has the following advantages:
WellFix FN is added to cement tempering liquid. Recommended concentration of the reagent WellFix FN is from 1.5 to 3.5% to dry cement weight, depending on the type of cement slurry and the ambient temperature.
