Coal Fly-Ash Utilisation in Greece

1. INTRODUCTION A large quantity of fly ash is the inevitable by-product of Greek lignite burning, due to its high ash content. The total annual ash production for the last two years was about 10x106 tons, of which 7.6x106 tons are produced in northern part of Greece and 2.4x106 tons in southern part of

CONCRETE Optimizing the Use of Fly Ash in Concrete

The calcium content of the fly ash is perhaps the best indior of how the fly ash will behave in concrete (Thomas 1999), although other compounds such as the alkalis (Na 2 O and K 2 O), carbon (usually measured as LOI), and sulfate (SO 3) can also affect the

Professor P. P. Edwards F.R.S. - Research Guides

These processes all cost energy and require extra operation input. The capture of CO 2 from flue gas is a highly energy intensive process and, of course, CCS also gives rise to daunting social problems associated with burying huge quantities of CO 2 .
