DETERMINING THE IMPORTANCE THE INFLUENCE OF TECHNOLOGICAL FACTORS ON THE RESTORATION REINFORCED CONCRETE STRUCTURES

Abstract

The article made an analytical study, by expert estimates, the determination of the importance of technological factors that have the greatest impact on the physical and mechanical properties of recovered parts of concrete structures. Technological factors were identified during the analysis of scientific literature. For the consideration of the experts was presented eight technological factors, namely: the stiffness, the repair mixture; seal; thickness of the recovery layer; the ambient temperature when performing rehabilitation works; condition of the surfaces of the concrete samples (the surface can be cleaned, stripped, with notches artificially destroyed...); the method of preparing the repair surface (use of contact layer); moisture content of the repair surface (dry, damp, wet); provision and maintenance Department relative to the horizon line (the position of the top "floor"; the side – "wall"; bottom – "ceiling"). The information obtained from experts, were edited on the basis of mathematical (statistical) method. The calculated estimate of the average degree of agreement of opinions of all experts and assessment of the significance of coefficient of concordance. Determined weight factors are considered: preparation of the repair surface; position of the repair site relative to the horizon; the state of the surfaces of the concrete samples (the repair surface is not cleaned, cleaned, with notches artificially destroyed); the stiffness of the mixture; sealing; moisture repair surface (dry, damp, wet); the ambient temperature when performing recovery operations and the thickness of the recovery layer.
