Effect of montmorillonite as additive on the properties of cement-based composites
The aim of this study was to investigate the effect of montmorillonite as additive on the properties of cement paste and mortar. Montmorillonite was used at 0%, 5%, 10% and 15% additive by weight of cement, and the water/cement ratios of 0.45 and 0.55 ...

Properties of bio-based gum Arabic/clay aerogels [PDF]
Lightweight bio-based aerogels from sustainable gum Arabic (GA) and sodium montmorillonite (Na+-MMT) clay were prepared by means of a simple freeze-drying process. GA/clay aerogels showed high porosity (87.9%–94.9%) of mainly open type and the mechanical

A capsule‐shaped silicate clay (H‐ATP‐N2) rich in protonated edge hydroxyl groups (‐OH2+) is synthesized through a two‐step process involving microwave‐assisted acid treatment and N2 plasma etching to fibrous natural attapulgite. The H‐ATP‐N2 host inhibits the shuttle effect owing to the dominant adsorption mechanism–Lewis acid–base interaction between

Organic Derivatives of Montmorillonite
THE supposed analogy between hydrogen-saturated montmorillonite and a weak organic acid has encouraged several investigators, notably Berger1 and Deuel2–4, to attempt to esterify the montmorillonite acid using standard organo-chemical methods.
