To enable Cement Australia to offer a complete range of supplementary and associated products, we have a large number of specialised subsidiaries and associated companies that complement our core cement business.

These close associations ensure Cement Australia always delivers with maximum consistency and reliability.

Pozzolanic processes and distributes fine grade fly ash and other ash products from five coal-fired power stations in Queensland – Gladstone, Tarong and Callide.
