“…Differences of influences that distinguish the conditions under which the calibration dependence provided and real conditions of determination by the methods of NT in the design, are discussed in detail in [7][8][9][10]. The results obtained in these works indicate a significant uncertainty in the application of the standardized method [5], which led to a gradual transition to the use of ultrasound from the determination of strength to the diagnosis of costruction structure [11].…”

The article considers the problems of diagnostics of reinforced concrete structures and creation the generalized calibration dependence for the use of ultrasonic devices. The results of the study of the influence of some factors on the results of measuring the dissemination time of ultrasonic vibrations are presented. The study was conducted using devices "Pulsar 1.1" and "Novotest IPSM-U" in compliance with regulatory requirements. Statistical processing of the obtained results (with visualization) was performed using the software package EXEL. Processing of the obtained data confirmed the multifactorial dependence of ultrasonic measurements on the concrete surface. The lack of clearly defined conditions for measurements reduces the reliability of the results. The use of ultrasonic measurements to obtain absolute values of the properties of concrete is not adequate. It is proposed to make changes to the regulations regarding the limits of application of ultrasonic measurements.

Periodic control of concrete properties is based on the use of nondestructive methods. Periodic monitoring of the condition of structures often is performed using ultrasonic devices. The accuracy of determining the physical and mechanical characteristics (FMC) of concrete depends on a significant number of factors affect. This reduces the accuracy of the results by standard methods. Based on previous studies, the methodology for using ultrasonic non-destructive testing devices was improved. The research and verification of the improved methodology in a real building demonstrate the low complexity of the work and sufficient reliability of the results. Improvement of the algorithm for work and data processing will allow to offer a reliable methodology for determining the technical condition of the operated structures and for periodic monitoring the concrete properties. A methodology for periodic monitoring of concrete properties in structures has been developed. It is necessary to carry out.

Adequate reflection of material properties by modern methods and devices is difficult. In addition, standardized methods do not allow to build an automated system for monitoring material properties during operation. Developing a monitoring system based on proper determination of the physical and mechanical characteristics of structural materials while the structure is in use could ensure the trouble-free operation, as well as determine the residual life buildings and structures. The research results allow us to establish the compliance of the methods for determining the properties of concrete with the control tasks and determine the limits of applicability of research methods. It is necessary to improve the accuracy of determining the physical and mechanical characteristics of reinforced concrete structures. This can be implemented by improving the method of non-destructive testing, taking into account the influence of significant factors. Systems for monitoring the properties of materials based on improved non-destructive testing methods allow to provide the SMART HOUSE system with sufficient stability and durability.
