University of Wisconsin-Milwaukee engineers have developed an ultra-strong superhydrophobic concrete. It is distinguished from ordinary concrete by the presence of special microfibers that prevent water from penetrating inside. This structure makes concrete more plastic and eliminates the appearance of cracks that destroy it.
When creating the fibers, superhydrophobic additives were used based on siloxane compounds, which form a silicone base mixed with special powders. The result is a surface that is virtually invulnerable to water.
Comparative tests have shown that new concrete is 200 times more ductile and withstands compression 4 times more than existing concrete grades. This will extend the service life of concrete roads and water pipes from 30-45 to 120 years without maintenance.
