Clays for Low-Carbon Cements: Overview, Progress, and Challenges. [PDF]
Glob ChallThis review provides a critical overview of recent developments of activated clays to function as artificial pozzolans. After a thorough description of the clays that yield good pozzolanic performances, selected examples are given on thermal and mechanical activations. Chiefly, general correlations are extracted from reported data despite its scattered

Sepiolite organic modifiers effect on pet/sepiolite nanocomposites degradation
Polymer Testing, 2022 In this paper the effect of different organosepiolites on PET matrix was evaluated through the analyses of Melt Flow Index (MFI) and Intrinsic Viscosity (IV) of the nanocomposites. PET/sepiolite nanocomposites were produced through a two-stage process.

Silica-Sepiolite Nanoarchitectures
Journal of Nanoscience and Nanotechnology, 2013 Silica-sepiolite heterostructured materials have been prepared as novel nanoarchitectures by generation of SiO2 nanoparticles (NPs) on the surface of the sepiolite fibrous clay mineral. The synthetic approach implies the use of organo-sepiolites dispersed in isopropanol to which is incorporated a selected silicon alcoxysilane, such as ...
