According to new EN 197-5 is possible to combine clinker with blast furnace slag, silica fume,
pozzolana, fly ash, burnt shale, and limestone from 36 – 50% while clinker content should be from
50 – 64%. In this paper are presented results of laboratory testing concerning CEM II/C-M
(S+W) production where a sample is prepared by mixing 50% of clinker, 23% of calcareous fly
ash, 23% of granulated blast furnace slag, and 4 % of gypsum. The focus was on the physical and
mechanical properties of laboratory-produced samples in terms of the specific surface, specific
weight, setting time, and tensile/compressive strength. Besides the physical-mechanical
properties, the main chemical parameters are also determined (SiO2, Al2O3, Fe2O3, CaO, MgO,
SO3, Na2O, and K2O). The obtained results of CEM II/C-M (S+W) are compared with the results
of cement CEM II/B-W 42,5N.
