Fly ash market

The Fly Ash Market has been growing due to the growth in the construction industry, increasing focus on infrastructure and road paving, problems related to dumping fly ash, the promotion of fly ash by governments of various countries, and an increasing focus on the use of environment-friendly products.

Based on type, the Class F segment accounted for the largest share of the fly ash market in 2015 and is expected to witness significant growth in the coming years. It is generally low-calcium fly ash with carbon content varying from 5% to 10%. The use of Class F fly ash is mostly in Portland cement where it is used in mass concrete and high strength mixes. It is also suitable for concreting in summer as it moderates heat gain during concrete curing.

The growth in the consumption of cement and cementitious materials from the construction sectors in Asia-Pacific and North America regions has driven the demand for Class F fly ash.

Based on application, the Portland cement and concrete accounted for the largest share of the fly ash market in 2015.

Fly ash is added to concrete to make it more durable and strong. Fly ash has low unit weight. On a pound for pound basis, fly ash contributes 30% more volume of cementitious material per pound compared to cement, and is a suitable material to partially replace cement in construction activities.

The increase in the construction expenditure in the Asia-Pacific region due to the rising demand for residential and non-residential buildings, will increase the demand of fly ash in Portland cement and concrete applications.

Asia-Pacific dominated the fly ash market in 2015 due to the increasing demand for fly ash from developing economies, such as India and China. China is the leading consumer of fly ash in the Asia-Pacific region, followed by India. Industrialisation has fuelled urbanisation in China and India through the migration of rural populations to urban areas and the development of towns into cities. As a result of this steady economic growth, construction activities have increased, leading to an increased demand for fly ash.

Key players operating in the market include Boral Limited (Australia), Headwaters Inc. (U.S.), CEMEX S.A.B. de C.V. (Mexico), Lafarge North America Inc. (U.S.), Charah Inc. (U.S.), Separation Technologies LLC (U.S.), Aggregate Industries (U.K.), FlyAshDirect (U.S.), Salt River Materials Group (U.S.), and Ashtech (India) Pvt. Ltd. (India).
