Characterization of organo-mineral cement materials

International audienceConclusion: A multi-scale characterization of building material is essential to optimize their properties and was sucefully performed by coupling different electron microscopy techniques. Hydrates morphologies, effect of the addition of latex on the cement microstructure were characterized. Full scale analysis is still under completion CONTEXT-MATERIAL Whatever the applications biomedial, tranportation, energy or construction; there is a lack of knowledge on the true organization at the nano scale of mineral and organic phase (qualitative image, together with quantitative analysis). This study was focused on the characterization of cementitious materials, and mainly on organo-mineral composite. Many innovative applications in the field of high-performance construction materials and building insulation systems are under developpement The addition of an organic phase in the form of a latex suspension may improve mortar functional properties (rheology, substrate adhesion hygro-thermal). The mechanical properties are also upgraded, and in particular the crack resistance. The latex addition effect should be characterized at different scales and therefore require the use of different electron microscope techniques
