RESEARCH AND DEVELOPMENT

1. Converting waste through micronisation and calcination the diamond saw slurry and crusher dust to metakaolin that can be used as a replacement for flyash in concrete.

2. Leaching clays from the siltstone to produce pure silica.

In 2017, Eidsvold Siltstone secured a government grant to conduct research into the feasibility of turning siltstone powder into metakaolin - a cement strengthener used in Europe and the US.

The research was undertaken with Queensland University of Technology (QUT) and found that siltstone powder is an excellent and green precursor for cement. 

For more information about the project, read the article Business Turns Dust into Profit 

In partnership with Centre of Infrastructure Engineering at Western Sydney University (WSU), we conducted a study into the use of siltstone powder.

The diamond cut Alumino Silicate bricks are calcined then polished. 


When calcined and polished, Eidsvold Siltstone becomes porcelanic.
