Description
Technical field
The present invention relates to containing inorganic binder or containing inorganic mortar with organic binder product, concrete or
The compositions field of artificial stone, specially a kind of cracking resistance anti-corrosion leak-proof guard method for concrete structural surface.
Background technology
Concrete is widely used in various buildings because of its good intensity and cheap cost.But concrete is because have
Hole and water can not be kept out and the intrusion of corrosive medium therein is dissolved in, such as the carbonization of the carbon dioxide being subjected in air is rotten
Erosion.Graphitic corrosion not only deteriorates xoncrete structure, but also can reduce the alkalescence of concrete, stiffener in destruction concrete
Passivation protection layer, cause steel bar corrosion, weaken booster action of the reinforcing bar to concrete, and iron rust expansion can also destroy coagulation
Soil, causes concrete cracking, peels off.In marine environment, when seawater or salt fog are penetrated in concrete, chlorion also can make
The passivation protection layer failure of reinforcing bar, causes steel bar corrosion.In graphitic corrosion and chloride ion corrosion and the environment deposited, the corrosion of reinforcing bar
Will drastically accelerate.Can be in area below freezing in winter temperature, concrete may also suffer the erosion of Frozen-thawed cycled.
Concrete easily tarnishes because having hole, long mould, not only affects attractive in appearance, it is also possible to increase concrete
The corrosion rate of material.
In existing building trade, xoncrete structure protects multiplex organic material.Multiplex organic polymer is protected in antiseepage
Water-repellent paint, it has preferable antiseepage protective effect to concrete surface, but antiseptic effect is not good.The multiplex latex of anti-corrosion protection
Paint, it has certain anti-corrosion protection effect, but the effect on driving birds is not good because impermeability is low to concrete surface.Because it is relatively costly and compared with
The epoxy resin that uses less, polyurethane coating have after preferable anti-corrosion leak-proof effect, but its solidification and become fragility, concrete substrate because
Expand with heat and contract with cold or its drawing crack is easily caused its shielding failure by normal design variations.Additionally, these organic materials are generally resistance to
Time property is poor, easily aging being exposed in the environment of ultraviolet, hot environment, it is impossible to provide long-acting protective effect.
