On March 19, in Hanoi, Department of Science and Technology, Ministry of Transport organized a workshop on “Introduction of silicone technology protects concrete in traffic construction works.”
Overview of workshop
Our country has a lot of importantly reinforced concrete buildings that are stretching along the coast from North to South. With a tropical monsoon climate, rainy, sunny condition, temperature and humidity are constantly changing during the day, the large atmospheric salt, the structure can be quickly destroyed.
Therefore, protection and repair is to improve the life-span of the traffic works. It is the most important task in the national economy. Previously, the use of protective paint in concrete bridge is very popular. However, over time, membranes of thick paint have many errors, such as peeling, cracking or discoloration, etc
After years of use, the engineers in Sweden have found that the use of silicone waterproof technology is the best method for protecting concrete. After 15 years of using silicone technology protects concrete that still has a good quality. In construction, silicone is used to seal, flea loophole, waterproof, leak. With the advantages of excellent adhesion to a variety of materials, such as stone that achieves longevity for decades, silicone is used in the works will help reduce maintenance costs.
Some of the typical buildings used silicone technologies that have been tested to prove fruitfulness at least 15 years, such as Grondals bridge (Sweden), 16 bridge projects in Bavaria (Germany), Tsingma bridge (Hong Kong), etc. With the above advantages of silicone technology, in the future, needing to put this technology into the construction works of Vietnam in order to overcome the adverse natural conditions, contribute to the durable increase for transportation projects.
