The aim of the project was to use waste plasterboard in low-medium strength concrete mixes for foundations for minor roads and car parks.

As part of this project we had over 100 tonnes of a “cement” made that contained no Portland cement. It contained a number of secondary minerals including waste plasterboard. It was a grey powder that looked like cement. It set like cement but gave a lower strength.

This shows the new “cement” being used in a dry lean mix for a car park. Note that these mixes contain NO primary products such as Portland cement or quarried aggregate.

This shows a novel alternative for higher strength road construction. This semi-dry mix contains no aggregate.

When wetted (below) the mix makes a promising looking flooring grout.
