[V-141] Performance evaluation of excellent visibility spalling prevention method using fiber bonding even construction in one day
Keywords:Visibility spalling prevention, Tunnel, Reducing the construction time, Fire resistance, Gas toxicity test
We developed the spalling prevention method which has excellent visibility for covering concrete, and construction is completed in a day after the surface preparation. It is an effective method for the limitation at construction days like a tunnel. And deformed covering concrete can be checked during inspection because of using transparent materials after curing. Furthermore, since it use only glass-cloth and epoxy resin excellent in flame retardant property, it has excellent fire resisting performance and safe on disaster prevention in a comparatively closed space such as an in–tunnel space.
