SPRAYED FIBER REINFORCED POLYMER COATING FOR RETROFITTING AND STRENGTHENING OF THE CONCRETE STRUCTURES

摘要

For concrete structure repairing/reinforcing for construct more specifically the present invention relates to injection-fiber-reinforced coatings with civil engineering, when in jet stream sprays, it is high for being related to a reinforcing fiber (glass fibre), flexible polymer blend layer is by being arbitrarily arranged in repairing/reinforcing in this way, its reinforcing fiber (glass fibre) of content spraying mixture and flexible polymer and by volume containing 10 to 40% in a volume unit, and the length and reinforcing glass fiber of flexible polymer mix air while being ejected repairing/reinforcing one fiber reinforced coating of the injection for concrete structure and is included in involved in 15mm to a 60mm length. The present invention can increase lifting capacity, such as ductility of concrete structure, building structure, bridge structure, etc. can be easily used in it is different types of require to strengthen compensation, remuneration/reinforcing of construction period, such as a carbon sheet or a conventional and expensive structure without using a reinforcement can by low cost and with effect easily machinability is constituted.
