Recent Trends in Coal Fly Ash Utilization Across the Globe

Press Release   •   Oct 04, 2010 13:27 IST

Two major sectors of fly ash utilization across the globe are cement and concrete. A number of engineering and environmental benefits are also gained by using the ash instead of multiple ingredients for construction works. However, like most other useful items, it also has some drawbacks.

Major barriers in the utilization of such ash occur for the fly ash manufacturers in the field of marketing, transport, handling, storage, and environmental aspects. Some of the major environmental issues relate to the effects of increased carbon or the ammonia contents in the ash produced, and the potential mercury releases from it.

One of the major benefits of using fly ash in either cement or concrete is that it will considerably reduce the use of natural raw materials and in result will enhance industrial sustainability considerably. Avoidance of CO2 emission is another major advantage when such ash is compounded in concrete or cement.

However, one of the drawbacks in use of the fly ash is that where it is considered as only a waste or byproduct, its utility can be easily undermined. It is therefore necessary broadening the definitions and range of the potential markets for cement and concrete. Manufacturers and companies dealing in cement and concrete should understand that use of the ash as raw material in cement reduces the rigorous requirements in case of blended cement or concrete.

New combined process or total use of this type of ashes can produce high grade as well as expensive materials for use in multiple specialized constructions. Similarly, barriers in the marketing process for such products could be easily overcome using the process of partnership between the coal combustion product and utilities marketers on one hand and cement producers on the other. It is essential that fly ash is marketed as a product that is clearly defined for the targeted users that includes engineers and architects.

Storage dome that is large in size offers maximum capacity with minimum footprint. Purchasing and stockpiling of enough amount of fly ash over seasons when it continues to be inexpensive and selling out them when the demand curve in the market turns upwards would be good strategy for dealing in the product. Forecasting of seasonal demands accurately as well as integration of the ash marketing with coal procurement can easily optimize the supply to demands. Transport as well as storage is often the economic barriers for the fly ash manufacturers.

Used mainly for the alumina content it carries, fly ash is used in cement kilns. In addition to the alumina the ash also contains silica, calcium and iron improving the clinker quality. Lower alkaline content and fineness of the products helps the pursuit. Usually the rate of substitution is in the range of 3-5% of raw material produced.

Blended cement requires much greater quantities of fly ash. For instance; in Portland cement clinker the percentage could be in the range of 5-40%. Calcareous Class C ash is used for rapid hardening of hydraulic cements.

Only thing to take care is that the requirements in terms of ash quality are highly defined and the manufactures should do well not to forget this vital aspect.
