Abstract.
For a composite material, volume resistivity (ρv) decreases dramatically when a conductive filler is more than critical value, an insulator filled up with it becomes a semiconductor or conductor.
The log scale of volume resistivity (ρv) of SCB/UHMWPE and ACB/UHMWPE composite materials vs CB concentration are depicted in Fig.3 (a,b).
Interpenetrating network material can be acquired without chemical reaction.

So it is a feasible way to restore the strength by reinforcement.
4 Einforcement design
4.1 The recommended plan of Preliminary strengthening
Comprehending the site factors and after the various contrast demonstrates, we decide to choose the composite materials -- Fang Ren Glass Cloth to reinforce the structure【4】.
So we can get that it has good flexibility restore ability. 6 Conclusion After reinforced concrete bridge suffered the fire, the mechanical properties of materials will in great change, from the view of static force, it mainly includes: strength dropping causes to the decrease of the bearing capacity; Stiffness changes causes to the larger deformation, and then affect the normal use of the bridge.

The coating process is as follows; the amount of liquid volume that can be carried by the support
material is estimated by measuring the volume of water absorbed into the porous material.
The bright pieces of material at the entrance and exit of the chamber are slabs of porous material to make the flow uniformly distributed in the flow channel.
The dark colored blocks between the porous materials are catalyst coated support materials on which combustion reaction takes place.
For this experiment, 1 cm thick layer of glass wool was used as insulating material.
