Effect of sepiolite addition on fibre-cement based on MgO ...

Sepiolite in cementitious materials behaves as a rheological additive to enhance fresh and hardened state properties. Sepiolite has a thixotropic effect that improves workability, adherence to the substrate, pumpability and surface finish . In the case of fibre-cement (FC) products produced by a dewatering-pressing technique (Hatschek or similar), this additive has an important effect in the rheology of the …

Sepiolite | IMA Europe

The high surface area and porosity of sepiolite account for the remarkable adsorptive and absorptive properties of this clay. It adsorbs vapours and odours and can absorb approximately its own weight of water and other liquids. Sepiolite is a non-swelling clay and its granules do not desintegrate even when saturated with liquids.
