Curing Precast Concrete? - Markham UK

23/04/2020  Delayed ettringite formation (DEF) can be induced much later in the structure’s life, by excessive curing temperatures – typically while steam curing, but also by large-mass precast elements being cured within their formwork. This effectively builds a failure mechanism into the concrete, which displays itself sometime later, in a similar manner to ASR.
