How to Read a Cement Mill Certificate: Part 2 - NPCA

The cement mill certificate includes three performance tests that merit close attention: false set, Vicat setting time and strength. False set. False set is the tendency for cement mixtures to stiffen early, typically due to the sulfate in the cement reacting with the water to form gypsum crystals over the first few minutes of mixing.

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.


Re: Cement Shelf life - Page 2 of 4

The grindability index is often calculated from the number of mill revolutions required to achieve a predetermined cement fineness.(either Blaine or sieve residues) This can be determined by taking representative samples from the lab ball mill after successive incremental numbers of revolutions, and testing these samples for fineness.
