Study of the state of protective structures of irrigation system canals and their restoration by applying optimal compositions of concrete mixtures

Long-term operation of irrigation canals with protective concrete coatings is accompanied by partial or complete failure of their structures and elements. This state of affairs leads to an increase in water filtration in the canals and, accordingly, the loss and reduction of water volumes required for reclaimed land. The development, determination and use of concrete mixtures with increased strength to a certain extent can solve the problem of providing structures of concrete slabs and connecting joints that are resistant to creep, cracks and destruction. The compositions and proportions of heavy-duty concrete mixtures based on M400 grades revealed as a result of these studies to a large extent allow ensuring the strength, respectively, and durability of the structures of protective concrete coatings and joints of irrigation canal elements. The paper proposes the basics of technologies for the production of repair and restoration work using special machines, equipment and developed concrete mixtures.
