The authors examine the impact of dynamic loads produced on the strength and deformability properties of concretes and their micro-cracking. The experiment performed and analyzed by the authors consisted in the dynamic loading of a concrete sample that caused its destruction. The analysis of the experimental findings consisted in the identification of specific conditions of cracking, derivation of dependencies and compilation of charts. The following conclusions are made in furtherance of the authors’ analysis of the experiment in question: 1) experimental findings help identify the nature of influence of the stress state on the strength value, deformability and micro-cracking of concretes. For example, it is discovered in the process of the experiments that the lower bound of the microcracking dynamics increases more significantly than the prism strength. 2) Regularities of influence of the rise in the loading intensity produced on concrete deformation properties are identified. The key factor of the concrete destruction is not the nature of the deformation, but the value of the overall strain.
