Concrete is a porous material, and freeways fail when water seeps into concrete and then contracts and expands with changing temperatures. Water also corrodes the reinforcing steel bars inside the concrete, which expand and cause the concrete to fail.
A new study (PDF, 376k) from Jordanian researchers suggests there may be a way to effectively seal off concrete roads and other structures cheaply with sodium acetate, a potato chip ingredient that provides a tangy snap.
