Elemental zonation in marine concrete
Open accessAbstract
This paper presents a large collection of microstructural studies on concretes exposed to marine environments for periods between 2 and 34 years. The phase changes were studied using optical as well as scanning electron microscopy. A total of 21 concretes, taken from 9 different locations along the Norwegian and Danish coastlines, were investigated. Chemical zonation and mineralogical zonation were observed in the surface regions of marine-exposed concrete. Three zones were found irrespective of the age, location or binder composition: a magnesium-rich zone, a sulfur-rich zone, and a chlorine-rich zone. The absence of major damage indicates that the observed phase changes led only to minor scaling. This suggests that, rather than sulfate attack, sea water merely causes sulfur enrichment.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
