Une simulation en béton

Abstract:
La matière la plus fabriquée par l'homme se met enfin à nu. On savait que le ciment, une fois mélangé à l'eau et solidifié, n'était ni ordonné comme un cristal ni déstructuré comme le verre, mais organisé en « grains » de quelques nanomètres de diamètre. En revanche, la structure exacte des grains résistait aux investigations des chercheurs. Grâce à une simulation numérique inédite, une équipe internationale associant des chercheurs du Centre interdisciplinaire de nanoscience de Marseille (Cinam)1 et de l'Institut de technologie du Massachusetts (MIT) vient de lever le mystère : chaque grain est un empilement de feuillets à l'intérieur desquels les atomes sont disposés de manière désordonnée. C'est ce mélange d'ordre et de désordre qui confère sa solidité au matériau.
