Structural retrofitting using FRP laminates

Cut the precured FRP laminate according to the design size. When cutting, some carbon fiber laminate should be lengthened about 150 mm for normal tensile bond strength test, taking into account the need of field inspection.

The effect of bonding steel plate reinforcement

If the area of a single empty drum is less than 10,000 mm2, it can be repaired by filling glue with borehole injection method; if the area of a single empty drum is more than 10,000 mm2, it should be removed and re-pasted steel plate with structural bonding adhesive, and re-checked and accepted.

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.

FRP strengthening concrete slab

Furthermore, FRP fabric is pasted at the bottom of the floor with a certain spacing, so that some floors are covered by FRP, while others are not.

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.
