G o ł a s z e w s k a were mixed with two ground limestones of various origin and grain size, in the amount of 6%, 10%, 20% and 30% of the cement mass. Thus obtained mortars have been subjected to rheological tests in a rheometer after 5 and 60 minutes from the moment of adding water to the binder. 2. EXPERIMENTAL PROGRAM AND RESULTS
