C 3 S. The presence of pozzolanic materials affects many aspects of C 3 S hydration, i.e. the kinetics of reaction, formation of portlandite and composition of the hydrates. The determination of the heat evolution rate is a sensitive and useful tool to characterise the way in which pozzolana influences the early hydration of C 3 S. Figure 10.17 shows that pozzolana modifies the

Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new
Autoclave (Alpha Hemihydrate) The chemical structure of alpha gypsum (CaSO4 1 / 2H2O) is the same as the beta plaster. There are differences in crystal structure resulting from the production process. For the production of alpha plaster high pressure autoclave kiln is used. Autoclave is a word of Greek origin and means self-locking.
