For the needs of the analysis, the data from the Report on testing of control concrete cubes were taken, the basic characteristics of hardened concrete are also classified. Statistical analysis of the date of concreting, age of samples, composition of concrete, volume mass, pressure strength, required concrete marks etc have been carried out. The statistics showed that the most commonly used cements were the following markings: CEM II A-M (V-L), CEM II A-M (S-L), CEM II A-S, with the highest share of concrete mark MB 30 with 66,8% and MB 40 with 14,3 % stake.
