Nano-Engineered Concrete Sealer: Building Optimistic Future of the Construction Industry

Photo credit: Washington University Researchers at Washington University (WU) have developed a nano-engineered sealer that can prevent concrete from damage. The sealer protects concrete from deteriorating after exposure to salt and water.  In laboratory studies, the sealer showed a 44 percent improvement against the damage due to salt and a 77 percent increment in water-repelling abilities. This study suggests new approaches to deal with infrastructure problems in the U.S. "We focused on one of the main culprits that compromise the integrity and durability of concrete, which is moisture," said Xianming Shi , study lead author and WU professor. "If you can keep concrete dry, the vast majority of durability problems would go away." Most of the infrastructure in the U.S. was developed in the mid 20th century and now is at the end of its lifetime. Since the late 1990s, the American Society of Civil Engineers has released reports on the U.S. infrastructure every four ye
