THE DEVELOPMENT OF THE INNOVATIVE METHODS CONCERNING ULTRASONIC DIAGNOSIS OF HYDRAULIC STRUCTURES IN MELIORATION SYSTEMS
The results of the comprehensive analysis concerning the influence of water saturation of concrete upon its strength properties and propagation velocity of ultrasonic waves at above-zero and below-zero temperatures are represented in the article. The correlation between the ultrasonic waves velocity changes in concrete and moisture at above-zero temperatures was established. This makes it possible to solve the problem of timely year-round instrumental inspection of meliorative hydraulic structures in order to prevent some emergency situations.
