Can I Use An Old Bag Of Cement? - Renovate Forum

14/12/2009  No. Minimum interaction, me and cement, I reckon is the best thing.

Wonder how fresh that is. 14th Dec 2009, 09:38 PM #8.

You have to cover the bags of cement/concrete every time it even looks like rain. There's not much worse than having to throw away a pallet of 60 bags of rock you paid good money for. Once it gets hard it's totally useless, there's no going back or making it usable

The shorter answer: If the cement has been kept unopened, very dry and hasn't gone hard, it might still be OK to use, but you should always wear suitable waterproof gloves and other PPE when handling cement to prevent alkali burns and dermatitis anyway.
