At the height of their use, coal-fired power stations produced more tonnes of coal derived fly ash CFFA than there was an offtake market for, so large quantities were placed in stockpiles or sluiced to lagoons, which were usually situated on power station land.
Preliminary findings show strong potential for recovered fly ash in unlocking a low-carbon future.
Research from the University of Dundee suggests that CDFA could be a valuable component in low-carbon concrete. The study, in collaboration with several organisations, is examining CDFA’s performance in concrete durability and long-term exposure tests.
Unlocking fly ash stockpiles to create low-carbon cement.
