Concrete chloride and experimental analysis of For reinforced concrete structures, chloride ion is strong to go to the ions in reinforced surface adsorption local passive films that help you make the registry's pH value quickly to make steel pH value reduced to 4, the following compromise passive film on the surface of reinforced so that it bared its iron chloride corrosion products does not constitute, in corrosion nor consumed in the process, but for the generation of corrosion intermediates play a catalytic on the beam and plate, by different column concrete construction section more,, the adoption of samplingXFluorescence Analyzer test on concrete samples for analysis, chloride content ~ , below the literature[2]Mild salt spray area Rewetting environment concrete chloride limit of and, therefore, be excluded if concrete material overproof chloride ions on the influence of the the beam sampling deep reinforced round face remain intact or you can verify that this the same time, on the same core samples of the outer and inner deep concrete test scenario, the outer layer of chloride ion content than deep inside, and you have verified the concrete CL salt spray on concrete cover a smaller reinforced . 其他因素 Design factor 文献[2]Of the view that General mild salt spray, plate, beam-column component layer of protection shall not be less than, respectively No darker than和 (40 mm, and the engineering design file plate, beam-column protective layer settings respectivelyChina's largest 和The 25 mm Document , is[2]Requirements for level; in addition, in view of the special mild salt spray area of architecture, design files only requires the use of water-proof, such as concrete, rust, and other additives have not been clearly above design mistakes as after the projects used of insufficient durability “ defective ”. Construction factors Construction document , the inspection of construction time is7月~9At the end of , beam and plate batch reinforced for admission for hours at7In the middle of the month, the time for concrete pouring9At the end of the month which is reinforced in the storage site for more than two data showed that the region's air humidity in 70% ~ 90% between , and sooner or later there is often diffuse, combined with the sea fog beam sampling and deep reinforced local construction reinforced storage conditions, can infer in the beam and plate in front of reinforced concrete pouring into the salt spray erosion is subject to varying degrees of corrosion occurs, deep reinforced samples in the beam intercostal there is both a rust spots.由第2Festival in construction process, most regional floor, protective layer of beam-column Stirrup obviously welcomes the carbonation side has never enough “ residual carbide ” [4], resulting in the removal of blunt steel soon to enter the activation state, on the basis of rust, corrosion and rapid development of the protective layer, which in turn caused the cracks, salt spray and CO2 establish invaded the reinforcement corrosion Of environmental assessmentThe building area without obvious industrial pollution, garage utilization is low, the room is not other pollution the project site during the sea fog over campuses, metal and glass building interior accessories the dew or water film and cause surface with this article section of test results of the analysis, salt spray on accelerated rebar catalytic role is not to be ignored, particularly Mr Leung on the underside virtually unprotected been discussed above, the reinforcement of the principal causes severe corrosion is reinforced protection during the construction of storage is ineffective due to corrosion, reinforcement of preliminary construction is finished as a result of concrete cover is too small, cause serious reinforced concrete carbonation, speeding up the rate at which reinforced blunt removal, reinforced along the axis crack accelerates chlorine-containing salt spray erosion Rebar and CO2Alkaline environment in and these factors together, reinforced a serious . rehabilitation schemeBy section 4 of the analysis of the reasons for all we know, the work shall be for a number of factors affecting the aforesaid on the durability of reinforced concrete structure repair[2]And bearing capacity strengthening, striking a removal of the original chloride on the impact and recovery, reinforced in strong environmental around while the overall structure of the work performance and durability of reinforcing capacity on board respectively, shear and bending strength, post classification shear capacity reinforcement, specific measures such as a table is shown below.表 Component measures the repair processComponent and damage types Repair measures durability or bearing capacity of -Liang, column Remove surface Interior layer, followed by two anti-rust impregnating agents to prevent internal rust spots. Reinforced area injury rate≤5% In addition to the chisels, reinforced the outer layer of concrete eliminate the effect of reinforcing steel rust, derusting reinforced surface; Jet C35Fine aggregate concrete cover depth, supplementing, ease of maintenance. 请去这个网站：
