The effects of limestone addition, clinker type and fineness on propertiesof Portland cement

Full factorial experimental design was applied to evaluate the effect of 5% limestone addition on various properties of cement in relation to clinker type and fineness. Two clinkers, differing only in lime saturation factor ( LSF), were used, and cements with two levels of fineness were prepared. The experiment was performed in real-scale conditions on a ball mill with a ca pacity of 15 t/h. Effects of different factors on compressive strength, hea t of hydration, setting times and water demand as well as the interactions between factors were evaluated. (C) 2001 Elsevier Science Ltd.
