摘要：

Provision of reliability of structures is an important issue at the designing stage. One of reliability aspects is durability. In order to estimate the durability of reinforced concrete it is required to apply standard procedure of calculation which, according to SNIP Regulations 2.03. 11-85 Protection of Engineering Structures against Corrosion, can be implemented with the use of means of primary and secondary protection(1). A peculiar feature of buildings with built-up or monolithic framework is that the major portion of reinforced concrete items remains in the structure of multi-layer walls and cannot be reached for renewal of the means of secondary protection. That is, in order to provide durability of structures it is possible to rely only on the means of primary protection. The article discusses estimations of parameters of concrete protective layer (its thickness and density), based in numerical solution of differential equations, which describe carbonization and guarantee protection of reinforcement against corrosion for the design operation lifetime of structure.
