Reinforcement of Reinforced Concrete Structures: Underwater Applicable CFRP Grid Reinforcement Method
It is a method for reinforcing concrete structures in water inexpensively without draining.
The underwater applicable CFRP grid reinforcement method is a technique that provides a cost-effective solution for aging deterioration and insufficient seismic strength in reinforced concrete structures such as bridge piers located underwater. The method involves adhering a lattice of carbon fiber bundles (CFRP grid) that has been impregnated with resin to the surface of the structure using a resin layer that cures underwater, thereby reinforcing the structure. Both the CFRP grid and the underwater curing resin have long-term durability. 【Features】 - Reinforces concrete structures underwater - Can be reinforced inexpensively without drainage - Long-term durability with CFRP grid and underwater curing resin - Carbon fiber can reinforce with high strength and minimal thickness - NETIS registration number KT-100101-A For more details, please contact us or download the catalog.
