A professional body realises its dreams

Dry shrinkage of concrete made from recycled materials

Transformation beyond the equity scorecard – Part I

In this article, MQ looks at how the industry has changed over the few decades, and reviews a report from Sir Rupert Bromley some 30 years ago, only to find that many of the challenges in those days still apply today.

This technical trial which was conducted in Australia by the University of Wollon- gong’s Bradley Whiting, Timothy McCarthy and Eric Lume, describes the procedure and results of a range of experiments conducted on a commercially available recycled concrete aggregate (RCA).

This paper provides qualitative insight into the initiatives employed and challenges experienced by mining companies in a quest to transform the mining industry; contextualising the challenges experienced by industry participants in their quest to transform.
