摘要：
In CaO-SiO2-Al2O3-Fe2O3-SO3-CaF2 systems, three kinds of quick cements from different clinkers were produced (C3S-C11A7.CaF2-C2(A,F), C11A7.CaF2-C2S-C2(AF) and C4A3s-C2S-C2(AF)). 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 ssD,2h = 7-28 N/mm2 and after 28 days ssD,28d = 45-64 N/mm2. 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-degrees-C and 20-degrees-C) and the setting process of quick cements, as well as the carbonization of quick cement mortar were investigated and discussed.
