Abstract

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.
