How can the crack width be measured in self sensing concrete?

02 February 2014 1 749 Report

For quantitative measurement of cracks in concrete.

Defferent methods were developed to evaluate surface-breaking cracks in in-place concrete structures.The following study demonstrates that the air-coupled sensors substantially improved the test speed measurements of in-place concrete structures compared to the contact sensors.
