Thank you for your medical query at AskTheDoctor.com
I understand your concern.
It seems like you end up developing an allergic reaction to the cement. It is very difficult to treat such allergies since you will always be exposed to cement at workplace.
But you can try with Tab. Claritin ( Loratadine ) 10 mg once daily at bedtime for 7 days and see if it recurs again. You can always use a personal protective equipment like a mask regularly to make sure you are not inhaling anything to limit the exposure.
Hope this was helpful,
