Calcium chloride is the most commonly used accelerator.

Prevac,

 

While Michael is correct that Calcium Chloride is the most commonly-used accelerator , it is extremely deliquescent.

 

Using it in the dry form may result in the formation of lumps in the cement, depending on whether the cement is to be stored for a prolonged period, or used immediately.

 

Best Regards,

 

Ted.
