Structural steel plate adhesive should be strictly tested

To the design of structural steel plate bonding adhesive use fixed number of year for 50 years, should pass the wet and heating ageing resistance and long-term stress resistance ability test.

Carbon fiber fabric reinforced concrete column

CFRP fabric reinforcement of reinforced concrete columns can change the axial stress state of concrete into three-dimensional stress state, and improve the bearing capacity and deformation capacity of confined concrete

Introduction of new technology for FRP strengthening

FRP composite strengthening includes two types: carbon fiber reinforced polymer(CFRP) fabric and carbon fiber reinforced polymer (CFRP) strip. Compared with traditional reinforced concrete or steel-bonded concrete, carbon fiber has the advantages of space saving, simple construction, no need for site fixing facilities, easy construction quality assurance, no increase in structural size and weight, corrosion resistance and good durability.

Concrete beams strengthened with FRP wrap

FRP wrap has been widely used to repair and reinforce concrete structures in recent years because of its high strength-weight ratio, corrosion resistance and easy construction.

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.
