Performance of Cement-Based Materials in Aggressive Aqueous Environments MEng. F. Lucka ¿Leichthin¿Concrete and cement based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over
