Its general appearance is light to dark gray powder and the size is the same as silt. The specific gravity of fly ash ranges from 1.9 to 2.5. There are two types of fly ash: type “C” and type “F”. Type “C” fly ash has significant amount of free lime. This type of fly ash causes pozzolanic and cementitious reactions. Addition of fly ash to lime and cement can improve the engineering properties of soil like lime or cement. fly ash properties are highly variable and depend on chemical composition of coal and combustion technology Bitumen is a by-product that remains after distillation or evaporation of crude petroleum. Tar is the result of destructive distillation of coal and other…show more content…
