✦ Synopsis

In CaO-SiO2-AI203-Fe203-SO3-CaF2 systems, three kinds of quick cements from different clinkers were produced (C3S-CIIAT-CaF2-C2(A,F), CI1AT-CaF2-C2S-C2(A,F) and C4A3"~-C2S-C2(A,F)). Blast furnace slag and lime stone were added as interground additives to these quick cements (20% -50% weight). During the first 2 hours the compressive strengths of the quick cements reached gD,2h = 7-28 N/mm 2 and after 28 days BD,28d = 45-64 N/mm 2 In this paper the formation of cement clinker as well as the hydration behaviour, the development of strength, the pore structure (for a storage in water, in atmosphere and in an atmosphere of 1 vol.-% CO2; for a temperature of 5°C and 20°C) and the setting process of quick cements, as well as the carbonization of quick cement mortar were investigated and discussed. 802
