## ABSTP~ACT The relationship between specific power consumption (Id.~/t) and Blaine fineness attained during grinding of the Portland clinker is represented by an exponential function. This function varies by stages. For each stage the following equation may be written: In k~.~/t = a + bS, where

Subject of this paper is to investigate the effect of ZnO during the sintering process of cement raw meal. The effect was studied by means of differential scanning calorimetry and X-ray diffraction. Besides, the rate of CaO consumption during the sintering of raw meals was measured. Final discussion

The hydration of portland cement in presence of citric acid has been investigated. The results indicate that O.l% citric acid accelerates whereas too high a dose (> 0.1%) of citric acid retards the hydration. Electrical conductivity measurements of the paste indicate that in the presence of citric a

Crystallization of a liquid similar to that present in Portland cement at clinkering temperatures has been studied. Its composition (in wt %) is CaO = 54.8, A~203 = 22.7, Fez03 = 16.5, Si02 = 6.0. Prolonged crystallization or slow cooling yields the equilibrium phases: C3A, ferrite close to C,AF, an
