Methods for determining the basic physical and mechanical characteristics of concrete are based on tests of standard concrete samples. The smallest size of such samples is determined by five sizes of filler. Extraction of such samples from finished products is hindered. Previously, dependences making it possible to determine the modulus of elasticity of the samples, knowing the ratio of the solution to the filler were obtained. This ratio is determined by the side surfaces of the sawn samples. Concrete samples obtained by sawing standard samples were tested. The results of complex comparative tests of standard and small samples are presented. As a result of the study it is revealed that the strength of small samples does not exceed the strength of the standard. The behavior diagrams of the standard samples practically coincide with the averaged diagrams of the work of samples of small sizes. Test results show the opportunity to move from tests of standard samples of concrete to concrete samples of small sizes.
