It is mostly due to durability deficiency and lead to, the particularly more serious area of atmospheric pollution, most importantly in concrete-bridge
The reinforcement corrosion in portion leads to structure early damage, and this has become as global serious problems.
Existing highway bridge safety engineering is mainly around safety research such as bridge structure antidetonation, wind resistances, and rare concrete is rotten
The research of erosion focuses primarily upon air-free concrete and steel bar anti-corrosion material.Density concrete can ensure reinforcing bar and the less face of air
Long-pending contact, and the contractility of density concrete is obvious, in initial stage and the later stage of intensity formation, easily produces cracking,
Reinforcing bar at crack is under the erosion such as rainwater it is easy to destroy.Another way is to smear rush-resisting material on reinforcing bar, first
First rush-resisting material causes reinforcing bar and the bonding of cement to decline, and causes the reduction bonding ability to reinforcing bar for the cement;Meanwhile, antirust material
Material, in concrete construction, locally can produce destruction, and antiseptic power declines.Therefore, it is directed to bridge reinforcement and applies corrosion and ask
Topic, if a kind of anti-corrosion measure of environmental protection and quick way can be proposed, will be to construction permanent seal cooling, environmentally friendly science of bridge building
Have great importance.
