Bridge cracks repair methods

Once the crack appears, it will affect the structural durability, will directly affect the bearing capacity of the structure, and even endanger the safety of the structure. It is worthy of attention and should ascertain the cause of cracks,we must take appropriate measures to repair.

Difference between FRP strengthening and traditional methods

Why is CFRP reinforcement more and more popular among engineers? it increase the structure's crack resistance or shear capacity, and improve the strength, rigidity, crack resistance and elongation of the structure.

Why load is removed in the process of strengthening?

In order to make the new and old structure to bear force together, should first remove the original structure load before the reinforcement. It is a better way to reapply it after reinforcement.

Can FRP strengthening be interchangeable with steel plate?

Fiber reinfroced polymer(FRP) and steel plate reinforcement are all similar of bonding form and strengthening mechanism. Essentially, they are equivalent to increase the reinforcement of members, and they can replace each other in shear and flexural strengthening.

What is the difference between structural strengthening adhesive

The structural strengthening adhesive has high strength (compressive strength >65MPa, steel steel tensile bonding strength >30MPa, shear strength >18MPa). It can withstand large loads, and is resistant to aging, fatigue and corrosion. It has stable performance in the expected life and is suitable for bonding with strong structural member.

Reinforced beams using unidirectional CFRP fabric

Because of the insufficient bearing capacity of the original concrete beams, carbon fiber reinforced polymer(CFRP) fabric is used in the strengthening method.The lack of reinforcement area * reinforcement tensile strength design value is less than or equal to the carbon fiber cloth thickness * width * design value of tensile strength of carbon fiber cloth

Resin of concrete cracks, how to repair concrete cracks?

80% of the structural cracks are caused by deformation, and about 20% of the cracks are caused by load, and sometimes two kinds of cracks are fused together.Recommended crack repair products: HM-120ML crack repair adhesive, HM carbon fiber fabric, HM pre-stressed CFRP laminate system

Repair method of concrete cracks

We must first know the cause of the concrete crack before repair. If the cracks caused by insufficient bearing capacity should be repaired by corresponding methods, then choose appropriate reinforcement methods to retrofitting.
