This paper presents the results of the research that were performed in the Laboratory of Reinforced Concrete, Faculty of Land Reclamation and Environmental Engineering. The studies are based on theoretical aspects of the concrete prism bending resistance determinations. Using static analysis, the formula for bending resistance was determined. In the laboratory, Tests were performed on three standardized test-samples: three prisms made of concrete having the dimensions 150x150x600mm. In the first stage, non-destructive tests were made using the Schmidt sclerometer and the Pundit Lab device. Based on the formula was measured an approximate value of the loading force for which the effort is reaching the corresponding resistance of the concrete rank; this approximate value of the loading force was achieved by nondestructive tests. In the final stage, results validation was performed by effective test on three standardized test-samples concrete prisms. The samples were tested with a bending load up to 250 kN in the SERVO PLUS EVOLUTION universal pressing device. The three tests and the standardized test-samples concrete prisms were performed and made according to the actual Romanian standards.
