Monitoring of reinforced concrete structures on the base of non-destructive tests of concrete: control procedures, conformity criteria

The article deals with the monitoring of strength parameters of concrete in constructions carried out by nondestructive methods basing on the standards adopted in Belorussia, Russian Federation, and the European Union countries. On the basis of the statistics of the in-situ concrete testing, its being suited to the strength grade has been considered and the ways of improving the efficiency of the monitoring have been suggested.

Key words: cast in place concrete, strength, non-destructive test, methods, procedure, combination, code.
