Understanding the Basics of Coal Bottom Ash: A Vital Coal Combustion Product

by Navdeep Singh

Coal is one of the most recommendable natural resource that has been used for in form of fuel for energy and steam production for around more than one and half past century. Burning of coal in coal fired boilers, leaves behind the various types of ashes such as fly ash, coal bottom ash, boiler slag, flue gas desulfurization materials and other residues. Apart from fly ash, coal bottom ash generally considers as a vital coal combustion product which is durable supplementary cementitious material and has a considerable potential to be used as an alternative ingredient in manufacturing of concretes/mortars due to similar physical and chemical composition. This book briefly highlights the behaviour of coal bottom ash when used as an alternative for cement and fine aggregates in concretes and mortars with its brief applications. The utilization of coal bottom ash in raw form or in grounded form as an alternative supplementary cementitious material presents a viable solution for solving the major concerns like scarcity of dumping sites, several environmental impacts, health hazards towards human beings and reduction in overall production cost of concretes/mortars. Also, the appropriate recommendations of probable usage of coal bottom ash in raw or in grounded form in civil engineering industry and other engineering construction applications probably prevent the non-viable use of natural resources to some extent.
