Damage due to Delayed Ettringite Formation (DEF) can be severe, and can compromise the structural adequacy of an existing structure. This paper illustrates the severity of problems that can occur, outlines the diagnosis of DEF and the assessment of structures affected by DEF, and discusses some issues related to potential remedial works schemes. |
