Effect of composite anti-corrosion and rust inhibitor based on solid phosphating slag on concrete properties
In order to improve the durability of buildings under harsh environment,anti-corrosion and anti-rust concrete were studied.A new type of solid alcohol amine was prepared using triethanolamine,aluminum nitrate and Ca(OH)2 by chemical reaction.A composite corrosion-resistant and rust-resistant agent was prepared by mixing and milling solid amine,solid waste phosphating slag,gypsum and sodium benzoate in a certain mass fraction.The mechanical properties and anti-corrosion and anti-rust properties were also studied.The results show that the compressive strength and flexural strength of anti-corrosion and anti-rust concrete mixed with compound anti-corrosion and anti-rust agent are significantly increased,with an impermeability grade of P12.The carbonation depth is greatly reduced,and the anti-cold,hot,dry and wet cycle and anti-freeze performance are excellent.The steel bar has been immersed in seawater containing corrosion inhibitor for 2 years,and no corrosion is found.The anti-corrosion and anti-rust concrete prepared with compound anti-corrosion and anti-rust agent can effectively delay the corrosion process of building concrete.The use of solid waste phosphating slag to prepare anti-corrosion and anti-rust inhibitor can be used as a reference for the development of new anti-corrosion and anti-rust inhibitor.
