Results showed that increasing of fineness until 9000 Blaine resulted strength of 60 kg cm–2 at age of 2 days. Further increase in compressive strength of 90 kg cm–2 at the age …
The proposed model correlates the specific grinding energy, the clinker work index and the specific surface (Blaine) of a cement produced through fine-grinding in ball mills.
