    Spatial Microstructural Ordering of Expansive Clay Minerals by T. López-Lara, J. B. Hernández-Zaragoza, D. Carreón-Freyre, M. Cerca, E. Rojas-González, A. G. Minor Franco, G. Martínez-Barrera, R. Salgado-Delgado

    Published 2018-01-01
    “…The volumetric change within soils containing expanding clays depends upon their spatial ordering and their mineralogy. So this work studies the spatial microstructural ordering and mineralogy of different expanding clays in order to correlate them with some of their geotechnical properties (plasticity, classification, and expansion). …”
