The paper refers to laboratory tests of effects of various kinds of cement on chosen properties of C30/37 road concrete. Three kinds of cement were used: ordinary Portland cement CEM I 42,5 R, fly ash-Portland mixed cement CEM II/B-S 32,5 R and slag cement CEM III/A 42,5 N LH/HSR/NA. Recipes of the concrete mixes were designed and evaluated experimentally. Test samples were prepared in laboratory conditions. The samples were matured for 28 days in case of concrete made of CEM 142,5 R and CEM II/B-S 32,5 R cements and for 56 days in case of concrete prepared of CEM III/A 42,5 N LH/HSR/NA cement. The matured samples were tested for: compressive strength, tensile strength in bonding and split test, water absorption and freeze-thaw resistance. After final analysis it was found that each of concretes meets the requirements for road concrete listed at the GDDKiA technical specification [Ogolna Specyfikacja Techniczna... 2014]. In most tests the CEM III/A 42,5 N LI MISR/NA cement performed best.
