Fly ash concrete is designed in the same manner as Portland cement concrete. Generally lower water contents are required for a given slump. The slower strength gain usually associated with fly ash concrete requires that the water-to-cementing-materials ratio (W/CM) be reduced to provide the same strength at early age (e.g. up to 28 days) as Portland cement concrete.

Fly ash is fine ash collected from the flue gas after coal combustion, and is the main solid waste discharged from coal-fired power plants. The main oxide composition of coal ash from thermal power plants in my country is: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc.
There are significant differences in equipment of the conventional ammonia – soda process and the ammonium chloride producing soda ash process. For example, there is no ammonia recovery and therefore no distillation tower, likewise, no milk of lime and consequently no lime kilns which are also the source of carbon dioxide for bicarbonation.
