Key points of FRP composite strengthening
Before FRP composite strengthening, please reconfirm whether the concrete repair surface is clean and no foreign matter. After confirmation, make sure that the bottom glue is evenly applied on the top and bottom glue, otherwise there will be bubbles in the later carbon fiber composite materials.

How to arrange anchor bolts for steel plate jacketing
Bonded steel plate reinforcement is to use high-performance epoxy structral bonding adhesives to bond steel plate to the surface of concrete components, so that steel plate and concrete form a unified whole, using the good tensile strength of steel plate to enhance the bearing capacity and stiffness of components.

Strengthening of columns using FRP composite
The bond surface between FRP composite and concrete structure is a weak link in reinforcement. Orthogonal test can be used to determine several characteristic values of bond surface with high durability.

How to pull out the planting rebar
Planting rebar technology is an important branch of Post-Anchorage technology. By drilling, gluing epoxy anchoring adhesive and planting reinforcement on the original concrete structure, the new members are joined together with the original concrete base material.
