Reinforcement and inspection of cast-in-place concrete slab
In residential building project, before the construction of cushion layer and surface layer, cracks less than 0.3 mm were found in cast-in-situ concrete slab, and leakage was found after water injection. After core drilling, it was found that the cracks were caused by concrete strength and slab thickness not meeting the design requirements.

Seismic strengthening technology
The bonded carbon fiber reinforcement method refers to the bonding of carbon fiber sheets on the surface of concrete members with adhesive, giving full play to the tensile strength of carbon fiber, replacing steel bar. It is mainly used for strengthening the flexural capacity and shear capacity of concrete members.

Steel beams strengthened with CFRP plates
In recent years, FRP materials, especially CFRP materials, have been widely used in civil engineering. Although not as widely used as reinforced concrete structures, CFRP reinforced steel structures have also begun to be applied to bridges and housing construction.
