Caractérisation expérimentale des propriétés chimio-mécaniques de l'interphase pâte de ciment-granulat par MEB et nano-indentation
Abstract
This article presents an experimental study of the chemical and mechanical properties of the interphase cement paste / aggregate. The interphase zone is the zone of the cement paste which is in the immediate vicinity of the aggregate to a thickness of about 20-50 μm and which has different mechanical and chemical properties compared to the pure cement paste. Cement paste / limestone aggregate composite samples were fabricated to allow the study of the chemical and mechanical properties of the interphase. The cement paste is made of Portland cement with an W / C ratio of 0.4. Calcium concentration profiles around the interphase area show a high concentration of calcium due to the presence of portlandite. The nano-indentation tests indicate a zone of weakness at the interphase level.
