Application

Polycem Frost and Frost Light are used in casing cementing jobs on permafrost rock intervals: Polycem Frost is used for making grouting mortars of normal density, whereas Polycem Frost Light is used for making lightweight grouting mortars. Polycem Frost and Frost Light ensure the following advantages: technologically acceptable thickening and setting periods at subzero and low positive temperatures; these periods are easy to regulate by changing the setting retarder dosage; rapid cement stone maturing at low temperatures; weak heat extraction at hydration; strong frost and water resistance of cement stone; high sedimentation stability of grouting mortars.

 

Packaging

Polycem Frost is packaged in big bags or polypropylene bags with a polyethylene liner.
