Repair and Strengthening Reinforced Concrete Beams

Project

Beam strengthening and repair

Structural strengthening materials

High strengthening carbon fiber reinfroced polymer(CFRP) wrap

A grade carbon fiber adhesive

Carbon fiber strengthening process

The beam bottom is affixed with 2 layers of 200 wide carbon fiber fabric. The U-shaped hoops adopt 100 wide spacing and 200 equal distribution, and the top is pressed with a layer of 100 wide carbon fiber fabric battens.

Smooth the surface of the concrete with an angle grinder, clean the surface with a blower, apply carbon fiber glue, paste high-strength carbon fiber cloth according to the cross-section of the beam, clean the surface with a scraper until there is no empty drum and air bubbles

Construction Notes

1. Keep the concrete surface dry. The

2. Remove dirt, oil, and if necessary clean with alcohol.

Surface protection

After the end of construction acceptance, use 1:2 cement mortar for surface protection
