Description
Technical field
The invention belongs to power station steel-slag sand side concrete guide wall coating process technical field, more particularly to a kind of water power
Stand the nanometer protective coating method of steel-slag sand side concrete guide wall.
Background technology
Concrete due to its superior performance and economy, have become modern industry and water power, bridge, tunnel and
The essential construction material of civil buildings.Common concrete is usually to be pressed by binder materials (cement), water and thick, fine aggregate
Proper proportion coordinates, and mixing is into mixture, the artificial stone hardened through certain time.The corrosion of concrete structure oneself turn into
One global serious problems.
Analyze the present situation of developed country concrete erosion, by taking the U.S. as an example, about 250,000,000,000 dollars of U.S.'s whole year it is various
Inside corrosion loss, just up to 150,000,000,000 dollars of the loss of concrete structure, in order to safeguard that these concrete structures need cost
90000000000 dollars.Although the time of China's large-scale use reinforced concrete structure is later relative to developed country, now also
Through occurring in that a large amount of serious steel reinforced concrete erosion phenomenons, China's corrosion damage in 2010 is up to 1,000,000,000,000 yuan, and wherein reinforcing bar is mixed
Solidifying soil corrosion damage is more than 160,000,000,000 yuan.The loss that China is caused due to the corrosion in field of civil engineering every year according to statistics is reachable
180000000000~360,000,000,000 yuan.Meanwhile, China is currently under the extensive capital construction stage, if ignoring armored concrete
Etching problem, will certainly result in greater loss.So the corrosivity to reinforced concrete structure carries out research with great
Theory significance and realistic meaning.
The destruction of concrete structure, is broadly divided into the destruction of concrete itself and because the change of itself of concrete is made
Into the corrosion failure of reinforcing steel bar.Causing the factor of destroying concrete structure mainly has：Carbonization, the erosion of chlorion, sulfate
Erosion and the factor such as oxygen and water.The volume of reinforcement corrosion product (iron rust) is about 2.5-7 times of original iron volume, produced
The bulbs of pressure can cause the cracking of concrete, peel off, the generation in crack can cause the entrance of more corrosive mediums again, trigger more
Serious corrosion.
In recent years, in the groping of substantial amounts of scientific research and engineering practice, having worked out a variety of prevents concrete erosion
Measure, including：(1) change the mineral clinker composition in concrete, make it have stronger corrosion resistance；(2) in concrete
The additives and silicon ash, ground slag etc. such as middle admixture high efficiency water reducing agent, air entraining agent；(3) concrete proportioning reasonable in design, is improved
The compactness of concrete, to reach the target of enhancing corrosion resistance.(4) using types such as acrylic acid, polyurethane, chlorinated rubbers
Corrosion-inhibiting coating.But current concrete protection, some important concrete structures are particularly, the protection to concrete has more
High requirement.Such as power station steel-slag sand side concrete guide wall, above-mentioned traditional protectiving scheme can not fully meet it already
Composite request in terms of wear-resisting, water-fast, ageing-resistant.
