“…The cement production can involve high quantity of mineral additives of various origins since this economize fuel and natural raw materials due to use of by-products [1][2][3][4][5]. Production of cements with high quantity of mineral additives based on slags enable to increase volumes of cement and concrete production as well as to obtain high-performance concrete with low amount of Portland cement per 1 MPa of strength [2,3,[6][7][8][9].…”

Nowadays, it is acknowledged that the use of mineral additives based on ground slag is one of ways of resource saving and improvement of technical properties of cement composites. Mineral additives with fineness similar to the Portland cement fineness are often used to replace part of Portland cement. Two kinds of ultra-fine ground granulated blast furnace slag that differ in composition and fineness were studied in the paper. Water-reduction due to effect of super plasticizer in slag-Portland cement compositions with amount of slag up to 70% was studied. The results of reduction of binder quantity per 1 kg of chemical admixture due to significant water-reduction are obtained and analysed. Correlations depending on kind, amount and fineness of slags, as well as depending on mineralogical composition of Portland cement were stated. The ultra-fine mineral additives based on ground slag with high specific surface area can be used for significant reduction of compositional binder.
