If the terms bentonite and montmorillonite had both been coined late in the 20th Century, then it's possible that one would be saying that " Sodium montmorillonite is the name for the ore whose major constituent is the clay mineral, sodium bentonite."

This strategy could greatly benefit future construction processes because fracture toughness and elasticity of brittle cementitious materials can be largely enhanced on the nanoscale. Calcium silicate hydrate (C-S-H) is the binder in concrete, the most used synthetic material in the world. ... (Laboratoire Interdisciplinaire Carnot de Bourgogne

Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.

Building Materials and Construction: Calcium carbonate is critical to the construction industry, both as a building material in its own right (e.g. marble), and as an ingredient of cement. It contributes to the making of mortar used in bonding bricks, concrete blocks, stones, roofing shingles, rubber compounds, and tiles. ... Calcium carbonate ...

1. Introduction. Montmorillonite (Mt) is one of the main minerals found in bentonites, a naturally occurring clay. Mt is rich in stacks of layers/platelets held together by interlayer cations, by van der Waals forces, by electrostatic force or by hydrogen bonding inhibiting the solubility or miscibility .Moreover, Mt is a 2:1 layered silicate, implying that each layer is composed of two ...
