The pyrolysis of Portland cement followed by gas chromatography/mass spectrometry is described for the determination of chemical additives interground with cement clinkers known as grinding aids. This technique, coupled with in situ derivitization using BSTFA-TMCS reagent, has been found to be readily applicable for detecting phenol, along with five glycol and alkanolamine-type compounds in cement.

Authors Leslie A JardineAffiliation W R Grace and Companyadditives are the first and second laws of thermodynamics 'Everything tends towards a state with the lowest possible energy and the greatest possible disorder.' These general principles of nature are also valid for all aspects of grinding. Coated mill internals represent the lowest energy level for grinding without chemical additives.

It is possible to produce Class 52.5 N cement using additives to improve early strength and 20% fly ash. Loss in strength was observed in cement mortars produced using glycol-based grinding aid. Increasing the dosage of chemical additive also led to loss in strength due to nonhomogeneous distribution of hydration products.

World Cement between clinker and additives, the net saving is around US$1/t. Such strong arguments illustrate why market trend has turned toward fine or very fine cement, generally in the range of 4000 − 5000 Blaine, which the FCB Horomill plant achieves efficiently with no need for water injection or variable speed control of the mill.

Slag cement lowers the heat of hydration of a concrete mixture, which reduces the risk of early age thermal cracking, a major benefit for large or mass concrete placements. It lowers the total alkalis of a concrete mixture thus reducing the risk of alkali-silica reactions. Equally important, slag cement delivers improved workability.
