This paper reports on six site trials of sustainable concrete mixtures. The first three were concrete barriers for landfill, the fourth was a trench fill and the fifth and six were roads and car parks. The methods and mixtures evolved from moderately conventional designs containing ashes and slags and some cement which were blended at the plant to a super-sulphated pre-blended powder containing waste plasterboard and no cement. The strengths were not as high as a typical structural concrete but were fully adequate for each application. The paper concludes that while the technical viability of each mix was demonstrated, problems with insurance, capital funding, and environmental regulators have prevented their wider application.
