Characterization of carbonation-induced changes in crack features and geometry in hardened cement pastes

Research outputpeer-review

Abstract

Microcracks have a potentially significant influence on geochemical processes in cement-based materials. Microcrack properties (e.g. length, aperture, roughness) in turn are changed by various reactions, such as carbonation of the material. In this work, experimental crack geometry is analyzed statistically in order to understand how the crack features influence the carbonation process and vice versa. The surface roughness is a key variable because it substantially influences transport properties. In order to obtain different crack characteristics, surfaces with different properties are examined by vertical scanning interferometry. The first results on experimental, statistical and geometrical characterization of cracks are presented and discussed.
