Concrete Reinforcement    

Improved means of reinforcing concrete structures.


The technology relates to a means of reinforcing concrete structures by combining an externally bonded fibre reinforced plastic configuration with the mechanical fastening of cover plates on a concrete structure: adhesively attaching FRP onto the substrate concrete surface, attach the mechanical fasteners along.

The methods described are capable of mobilizing the full tensile strength of FRP materials. Also the additional cost is low since the preferred mechanical fasteners are relatively thin pieces of steel plate attached to the concrete structure with two normal concrete nails.

Primary Application of the Technology

Increasing the shear and flexural strengths of in-service concrete structures (e.g. ageing buildings, highways). It is useful for structural retrofitting, strengthening, and repairing of reinforced concrete structures.
