Hi there. Can anyone please help me.

I am trying to find a suitable accelerator to speed up the drying time of white portland cement. it needs to be a dry powder accelerator.

please advise.

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.
