Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a steel bar rust inhibitor and a preparation method thereof. Background technique

[0002] Reinforced concrete is the most widely used building material today. The premature failure of concrete structures caused by the corrosion of steel bars in concrete has become an important factor affecting the durability of concrete structures. In addition to the astonishing direct and indirect economic losses caused by steel bar corrosion, it also causes a large consumption of resources and energy such as steel, cement, sand and gravel. Some data show that in the United States, losses related to steel corrosion account for 40% of the total corrosion loss, and bridge corrosion damage alone accounts for half of it. The total corrosion loss of the United States in 1995 could account for 4.2% of GDP, more than 300 billion US dollars. The statistical data of some other countries th...
