ELEMENT DE RENFORCEMENT EN COMPOSITE FIBRES-CIMENT ET PROCEDE DE RENFORCEMENT DE STRUCTURES EN BETON ARME PAR UN TEL ELEMENT

摘要

The invention relates to an element (1) for reinforcing a reinforced concrete structure, of the plate or beam type to be assembled by bonding or anchoring to a reinforced concrete structure (PB, DB) to be reinforced, characterized in that it is formed from at least one mineral matrix (2) comprising short fibres and from stiffening reinforcements (3), the stiffening reinforcements (3) being prestressed in the mineral matrix. The invention also relates to a method of reinforcing reinforced concrete structures using such a reinforcing element.
