Carbonation profiles in cement paste analyzed by neutron diffraction

Abstract: The present work deals with the carbonation process in cement based materials such as concrete. In order to clarify the evolution of the two main phases involved in the process, portlandite and calcium carbonate as a function of depth, spatially resolved neutron diffraction experiments have been performed at SALSA diffractometer at ILL in carbonated cement paste samples. Specimens submitted to different carbonation processes, both natural and accelerated, have been analyzed with this non destructive technique.… Show more

“…This service life concept can be valid for any type of pathology that affects the service structure. In the case of reinforced concrete corrosion, however, service life will be defined according to a limit, i.e., a value that will, in turn, depend on project factors (type of structural element, safety coefficients, risks affecting safety) [11,[13][14][15].…”
