Caractérisation de l'expansion due à la réaction sulfatique interne à l'échelle de l'interphase pâte de ciment-granulat
Abstract
Delayed ettringite formation (DEF) is a slow chemical reaction that can be responsible for the degradation of a cementitious material, developing a swelling of the material and then diffuse cracking in the structure. The objective of this study is the experimental characterization at the local scale of the concrete reached by the DEF. The composite samples, of dimensions 10x10x30mm 3 , consist of a 15mm thick of cement paste placed in contact with a siliceous aggregate. The shape of these samples makes it possible to study the behavior of the interface between the cement paste and the aggregate. This zone is identified as a privileged zone of the development of the DEF. Given the slowness of this pathology, the experimental setting in the laboratory is accelerated by choosing conditions favoring the appearance of DEF. The tests are exploited at the local scale by measuring expansions by image correlation of the degraded samples and by scanning electron microscope observations. The results showed a greater expansion at the cement-granulate paste interface compared to the cement paste.
