THE EFFECT OF ADMIXTURES OF Na2CO3, SODIUM LIGNOSULPHONATE GRANULATED BLAST-FURNACE SLAG AND SILICA FUME ON THE PROPERTIES OF GYPSUM-FREE PORTLAND CEMENTS

F. Škvára, T. Slanečka, M. Frýbertová, P. Šimek

Using the method of mathematical planning of experiments, the effects of Na₂CO₃, sodium lignosulphonate, ground granulated blast-furnace slag and silica fume on the properties of pastes of gypsum-free Portland cements were determined. The respective effects differ from those on the properties of pastes of standard Portland cements and exhibit local extremes.
