Wasted opportunities
Article Abstract:
UK reserves of natural aggregate will run out in 2013. The Department of Environment is making moves to impose a waste dumping tax to encourage builders to use recycled demolition rubble and lightweight aggregate. Furnace waste is ideal for lightweight aggregate mix. The power industry dumps 7 million tonnes of it annually. Engineers are wary of leightweight aggregate as material has to be consistent and the level of impurities needs to be ascertained. Lightweight aggregates are in between 15% to 20% lighter but are not as strong as natural aggregates. They are also more expensive to produce.
