Abstract

Continuous microstructural changes on heating of hardened paste prepared from primary clinker of CA2 composition was studied. On heating period, several characteristic shrinkages and microstructural changes took place in the specimen due to the dehydration and recrystallization of calcium aluminates without regard to the accelerative shrinkage resulted from sintering. Though micropores formed by dehydration decreased with recrystallization of calcium aluminates, micropores formed by plate-type gibbsite in the hydrates were maintained up to the temperature at which CA2 becomes main phase and had influence to the microstructure of the final clinker.
