Structure first, anti-corrosion second.
        The importance of concrete preservation can be seen. What does the corrosion of concrete mean? What factors can cause concrete corrosion? What are the outstanding advantages of silicone nano-spraying water repellent technology in concrete preservation? How to evaluate the best silicone nano coatings?
1. What does concrete corrosion mean?
Federal Highway Administration (FHWA): More than 50% of the nearly 600,000 bridges in the United States have rebar corrosion, requiring $75 billion in maintenance costs per year, accounting for 1.25% of total annual construction costs.
According to statistics, the current cost of repairing concrete structures in Japan is currently 40 billion yen, and about 12.4% of reinforced concrete structures are damaged due to steel corrosion. Japan’s proud Shinkansen has been used for less than 10 years, and large-scale concrete cracking and denudation have occurred.
Second, what factors can cause concrete corrosion?


Due to the physical, chemical, and biological erosion of the environment, the concrete structure is degraded and the service life of the building structure is shortened. The main factors affecting the durability of concrete are: chloride ion erosion, steel corrosion, freeze-thaw cycle, carbonization, alkali-aggregate reaction, surface bio-erosion.
