(Urban, marine, industrial environments) The rehabilitation project in 4 stages • Establishment of the renovation project, • Implementation of the products, • Control and verification, • Monitoring and maintenance by the Client. 6 CARBON REINFORCEMENTS Reinforcement of concrete structures • Carbon fiber reinforced slat systems . • Uni-directional fabrics based on carbon, fiberglass. • Glued plates: the glued plate technique (called the hermit process) consists of gluing high elastic limit metal sheets to concrete using epoxy resin. Reasons for reinforcement - Increase in the durability of old structures or reinforcement for new requirements. - Inadequate plans or implementations. - Aggressive environment not foreseen during the design. - Increase in load requirements due to modifications in the use of the structure. The main advantages of reinforcement - Restores its initial resistance to a structure whose steels are degraded. - Increases the resistance of a structure which must receive additional loads. - Repairs structural defects in the case of cut, undersized or poorly positioned steels . - Reduces the deflection of concrete beams and improves service conditions. 7 FIRE PROTECTION FOR CARBON OR STEEL REINFORCEMENTS Fire protection from 1/2 hour to 3 hours by plates or projection.
