Global analysis of DEF damage to concretes with and without fly-ash
Autor: Nicole Pagan Hasparyk, Dioice Schovanz, Francieli Tiecher, Selmo Chapira Kuperman
Publikováno v: Revista IBRACON de Estruturas e Materiais, Vol 15, Iss 3 (2021)
Abstract Delayed Ettringite formation (DEF) is an internal expansive reaction that can damage concrete. DEF is strongly influenced by the temperature, above about 60-65°C, and other factors involving cement chemistry especially, but also its physica
