Abstract
In this paper a mathematical model for the control of Portland cement setting, using CaCl2 as accelerator, is developed and the importance o f chemical-mineralogical and fineness factors is pointed out. It is sh own that the ratio C(3)A/C(4)AF as well as the SO3 content are the pre dominant factors affecting the setting, while the fineness parameters, the specific surface and the fraction 3-32 mu m, also influence the s etting time. The effect of fineness parameters is more pronounced upon the final setting.
