The nano-engineered sealer makes concrete more durable
A nanomaterials-engineered penetrating sealer developed by Washington State University researchers is able to better protect concrete from moisture and salt–the two most damaging factors in crumbling concrete infrastructure in northern states.
In laboratory tests, the novel sealer was found to be 75% more effective at repelling water than a commercial sealer and 44% better at reducing salt damage. This work could be a way to combat the problem of aging pavements and bridges in the U.S.
Professor Xianming Shi of the Department of Civil and Environmental Engineering, who headed the project, said, \”We focused our attention on moisture, one of the major culprits in compromising the integrity and durability of cement.\” If you keep concrete dry, most durability issues will disappear.
