 — While inorganic colour pigments and natural organic dyes were among the first additives to be used in papermaking, present industrial practice is dominated by synthetic dyes. As discussed in the leather chapter, azo dyes are widely used for colouring products due to its high efficiency and the wide range of colours available in the market.

During the early 1900s clay became the dominant paper filler, and it remains a major resource for papermaking, especially in aqueous coating of paper, in addition to its continuing role as a papermaking wet-end additive (Harben and Virta 1999). In the US, the best clay deposits are located in Georgia and South Carolina.

 — The results indicate that RHA could be used as a sustainable and cost-effective alternative to conventional chemical additives with a positive environmental impact. This study may also provide valuable insights into the use of RHA in water-based bentonite mud and could serve as a guide for future research in the drilling industry.

Bentonite is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation …

 — The clay mineral bentonite has received a lot of attention for its potential to reduce the harmful effects of drought on soil health and biological activity.

 — As mentioned earlier, for dry-blended bentonite, the mixing procedure in the laboratory is the same as with any cement or blended cement (described in the referenced document). For pre-hydrated bentonite, the bentonite has to be completely hydrated (30 min is required), as any solid additive, in mix water prior to adding cement.
