On the Choice of Concrete Strength Inspection Methods of Ready-built Structures

Abstract

The classification of concrete strength estimation methods used in the inspection of buildings and structures is given. Instrumentation working hours, the cost of equipment and work performance for different methods are considered. Use requirements of nondestructive inspection methods for concrete strength estimation according to normative document are analyzed.The experimental data about measurement inaccuracy of different nondestructive inspection methods are given. Guidelines on the choice of concrete strength inspection methods for objects of the inspection of buildings are given.
