METHOD FOR REPAIR OF CONCRETE AND REINFORCED CONCRETE HYDRAULIC ENGINEERING WORKS AND STRUCTURES IN ZONE OF ALTERNATING ELEVATION OF WATER

摘要

FIELD: construction. ^ SUBSTANCE: method is carried out with the help of replacement of concrete damaged under action of alternating freezing and thawing by more frost-resistant concrete. Repair works are carried out so that thickness of new frost resistant concrete layer is equal or more than depth of concrete frost penetration in this zone under conditions of repaired structure operation. ^ EFFECT: high durability of contact zone and repaired section of concrete or reinforced concrete structure as a whole. ^ 5 cl, 2 dwg
