Abstract
The article deals with the research results of concrete destruction processes by different types of external impact. The materials were obtained by the Samara research school of architecture and construction academy. The paper analyzes the process of concrete destruction and determines its main flow stages, depending on the amount of released energy of crack formation. Initial parameters of concrete structure are proposed, including: surface energy, modulus of elasticity and Poisson’s coefficient. The authors paid special attention to kinetic characteristics including tendency of concrete crack formation and crack formation intensity. The combination of kinetic characteristics is given as a criterion for concrete durability assessment. Quantitative dependence of kinetic characteristics on moisture and porosity is confirmed.
