Typical chemical compositions of monocalcium aluminate (CA\*), dicalcium silicate (C,S), the ferrite phase and of pleochroite present in HAC clinker have been determined by electron probe microanalysis. The composition of stratlingite (C2ASH 8) present in five year old concrete samples prepared from

## 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
This paper describes the results of an investigation into the carbonation of high alumina cement set pastes both by means of carbon dioxide in water and also by means of alkali carbonate solutions. The rates of penetration of carbonation into cylinders is greatest for the strongest (O.1M) solution o
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
