Concrete skin detects cracking and chemical leaks
When concrete chemical and nuclear containment structures begin to crack or corrode, facility engineers need an instant warning. One way to monitor structural integrity of concrete is to measure its electrical impedance, which changes when the material cracks. However, this strategy suffers sensitivity issues. An international team instead is proposing to monitor both cracking and chemical leakage of concrete structures by measuring the electrical impedance of a multilayer coating applied to the structure’s surface (Struct. . . .
