Ball milling was used to improve the dispersion of GO in a cement matrix in a planetary ball mill. Results indicated that the process had a negligible effect on the morphology of the GO but led to a 6.8% increase of the number of defects it contained. By adding 0.03 wt.% GO to the cement paste, its compressive strength increased by 9%, and the ...

Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content. If a change is noted in the mill certificate, air-entraining agent dosages may need adjustment. Above 0.60%, alkali changes of 0.1% can be significant.

Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.
