Reinforced Concrete Durability Guarantee Strategy Based On ICCP-SS System

With the rapid development of China’s economy and the improvement of people’s lives,the basic building requirements have become even more urgent.This has led to the rapid progress and development of civil engineering.As a major demand for construction materials,the demand for concrete has greatly increased.In the material composition of concrete,sand is a sufficient part of the necessary building concrete,which mainly initiates the pressure-resisting effect.Therefore,under the premise of a large amount of concrete demand in the market,the amount of construction sand demand has also rapidly increased.Sand and sand used in infrastructure construction are mainly sand and sand,because river sand has the corrosion resistance that ordinary sand does not have,so it is the first choice for building sand,but it is basically difficult to purchase large amounts of river sand for coastal areas.In the production of concrete,the procurement of river sand is all from the inland transportation to the construction site.Long-distance and large-scale transportation not only wastes a long time,but also the impact of excessive exploitation of river sand on the environment is irreversible environmental damage.The main body of construction is to achieve development while protecting the environment.It is difficult for the government environmental protection department to permit the destruction of the environment.However,there are many sea sands rich in sea sand reserves at the seashore that can fully meet the demand for sand for construction in coastal areas.However,in Haisha,there is a large amount of sodium halide,which is often referred to as sodium chloride,and this material is extremely powerful.Corrosive,especially for buildings,the sodium chloride reacts with sand and gravel over time,seriously affecting the stability of the building,which is why there is no large use of sea sand.Chlorine can not only be The gravel reacts chemically.It also reacts violently to metal objects and corrodes metal objects.Untreated sea sand is strictly prohibited for use on buildings.There are many methods that can effectively prevent chlorine salt from reacting with sand and metal.One of them is what we often call the negative electrode that connects the circuit at one end of the metal,that is,the cathode of the external current loop to protect the metal.Impressed Current Cathodic Protection(ICCP),this technology can be very effective in preventing the corrosion reaction of reinforcing steel objects.Until now,cathodic protection technology is the only effective method to prevent metal corrosion.This is to solve the problem of chloride corrosion.The effective method.Although the cathodic protection method is currently the most widely used and is the most effective treatment method so far,the cathodic protection method can effectively prevent metal clothing,but it can not effectively deal with the metal that has already reacted.The service life of metal building materials that cause reactions is not guaranteed.The research direction of this study is to improve the long-term and effective stability of concrete,including the corrosivity of the steel structure of the building,as well as to increase the stability of the building structure.From these two points we propose a new building material composition system.This is the ICCP-SS system.This new type of system uses carbon fiber,a new carbon fiber reinforced polymer(CFRP),as a link to the system,and it is ICCP based on the conductivity characteristics.The auxiliary anode,which constitutes another type in the structure,combines the excellent properties of the excellent building mechanics such as CFRP,and both of them jointly establish a component containing a building content containing a high concentration of chloride ions(for example,the foregoing The mentioned sea-sand concrete(reinforced concrete)reinforcements and connectors are protected against corrosion and high-strength mechanical stability properties,so as to achieve effective protection of the durability of the main structure of the building’s full-life.This is also the focus of this study.The contradictions in the research process of this design,as well as the structural focus of the implemented functions,include the following aspects:1)Study the chemical reaction of CFRP structure in the environment of high concentration of chloride salt and the stress properties of the structure itself.As long as the experiment includes the intensity of the chemical reactions occurring in the special environment where the CFRP constituent structure is formed in a high concentration of chloride salt,that is,the difficulty in the formation of current,the sub-structures of the sub-structures are separately tested in the CFER as the overall structure of the common anode.In the case of changes in the electrochemical properties,it was analyzed that the CFRP structure can effectively solve the electrochemical properties of the steel structure.2)An example analysis of the performance of building materials under this system of ICCP-SS.The idea in the experiment was to use the ICCP-SS system consisting of a building block containing high chloride ions and using a common anode in a CFRP structure,to explore the corrosion resistance of this structure in the face of high chloride salts.
