Use of Fly Ash in Civil Engineering - Term Paper - TermPaper Warehouse

The tendency of fly ash to be less sensitive to variations in moisture content than natural soils can be explained by the higher void content of fly ash. Normal soils have 1 to 5 per cent air voids when compacted at maximum dry density. Fly ash contains 5 to 15 per cent air voids at maximum dry density.
