Fritz-Pak's Mortar Set Accelerator is a dry, white, powdered set accelerator packaged for use in pre-packaged mortar or concrete. It speeds up set times while increasing early compressive strength. Mortar Set Accelerator contains calcium, but no chlorides. Chlorides, such as the commonly used calcium chloride, promote corrosion in steel, promote efflorescence, and disturb color dispersion in colored concrete or plaster.

Unlike other non-chloride accelerators, such as those containing calcium nitrite, Mortar Set Accelerator is not hazardous. No special handling, storage or transportation expense is required.
