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.

Calcium silica hydrates, or CSH, are the key to cement’s solidity. As they form, they combine, developing tight bonds that lend strength to the material. These connections have a surprising byproduct — they make cement incredibly porous. Within the spaces between the bonds of CSH, tiny pores develop — on the scale of 3 nanometers.

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.
