Composite Polymer Coatings for Repair of Concrete Linings of Channels

Abstract

The paper is dedicated to the results of research on composite polymer material used for concrete casings repair. Field approbation of new material was carried out on the irrigation channel test site during the repair of concrete coating deformation joints and cracks. The paper provides the obtained theoretical formulae and results of water permeability calculation in concrete casing cracks with smooth and rough walls. A design chart for determining water permeability of damages in the form of cracks of various coating width on channel concrete coatings was obtained. A universal nomogram was obtained for determining the water permeability of damage in the form of cracks of various opening widths on the concrete coverings of channels.
