Good day all.

We manufactured a batch of Glass G cement on 27-12-2013 and when we were ready to pack it out yesterday we found that the cement was not flowing. We also noticed that a laboratory sample retained from the batch manufactured (stored in laboratory environmental conditions) also was a bit lumpy.

The following were checked and nothing out of the ordinary noticed:

  • humidity/moisture in transport and storage air
  • Milling temperatures
  • alkali levels in clinker
  • Gypsum purity

Can someone please guide me as to what else i can check to determine the possible cause of this phenomena?

Looking forward for your responses

Thanks.
