Externally Bonded Reinforcement for Strengthening Concrete and Masonry Structures

FRCM components: the matrix (a) and the fabric mesh (b).

FRCM U-wrapped for shear strengthening of a reinforced concrete beam.

Strengthening of masonry walls requires using a bi-directional fabric mesh.

Mixing of the matrix components is similar to other repair materials.

Wet the substrate surface to achieve a saturated surface-dry condition then apply the first layer of cementitious matrix.

The fabric mesh is gently pressed into the first coat of matrix.

The second coat of matrix is applied over the top of the fabric mesh.
