Abstract

The article summarizes experimental and theoretical studies on predicting the resistance of building composites to physical, chemical, and biological aggressive environments. Different ratios of the rates of mass transfer and chemical reactions in the composite can lead to a loss of its strength unevenly over time, with a gradual leveling (transition kinetic region), or evenly over the entire volume almost immediately after exposure to the environment (internal kinetic region), or from the surface (diffusion kinetic region). The given patterns allow to simplify the expressions for predicting the indicator of physical-chemical and biological resistance of construction composites. The dependences of the ratio of mass transfer rates and chemical reactions for predicting the physical-chemical, biological resistance of construction composites are shown.
