The article deals with the questions of concrete homogeneity, above all with possibilities how to verify this characteristic. We manufactured for this experiment two concrete blocks with dimensions 300×300×900 mm from concrete C 20/25 and then we determined their homogeneity using non-destructive and destructive testing methods. It is only a small part of experimental research, but it is possible to generalize research results and conclusions. We verified the concrete homogeneity in real structure using the ultrasonic impulse method – on columns of monolithic frame of car shelter.
