Figure 2 shows the structure relations for illite-rich illite–smectite. The Al–Si ordering implied by our model verifies that it can be viewed as interstratified packets of illite and R1 I–S ...

Project lead Dr. Chamila Gunasekara said low-grade illite clay does not normally bind well with cement and water, ... which points to better long-term reactions that help the structure stay strong.

Kaolin demand is gradually rising, with the market expected to reach US$6 billion by 2032. This research may also help create a market for illite clay.
