Following figures show an earth retaining wall before and after repair in Gifu, Japan. This wall had been damaged by alkali-silicate reaction, in the form of macrocracking. The use of a regular concrete for repair was beyond consideration due to expected reflective cracking. ECC was adopted to control the cracking of the surface layer. One year after installation, only microcracks less than 50 micro-meter in width could be observed (Rokugo, 2004).
