Flocrete CL50 is a liquid concrete admixture based on calcium chloride, specially designed to accelerate the setting time and increase early strength development of concrete, while also providing water reduction in the concrete mix.


Flocrete CL50 is available in 5 gal (19 litre) containers as well as 275 gal (1,041 litre) and 330 gal (1,249 litre) IBC totes. Bulk supply in tanker trucks is also available upon request.

  • Flocrete CL50 complies with ASTM C494, Type C and E.


Flocrete CL50 is designed for use in cold weather concreting or whenever accelerated properties of concrete are desired.
Flocrete CL50 may be used in all types of concrete except pre-stressed and other applications where chloride is not acceptable.


Flocrete CL50 is suitable to use in combination with other DCP admixtures to achieve specific working requirements, as long as they are added separately to the concrete mix.
