Pozzolanic properties of pulverized coal combustion bottom ash

Cement and Concrete Research, 1999
The pozzolanic properties of a coal combustion bottom ash were investigated. Plain pastes containing equal amounts of calcium hydroxide and bottom ash were prepared and analyzed at different ages for their strength and the calcium hydroxide consumption. At early ages, bottom ash does not react with calcium hydroxide.

Reuse options for coal fired power plant bottom ash and fly ash

Reviews in Environmental Science and Biotechnology, 2014
Reuse options for coal fly ash and coal bottom ash are reviewed in this paper. Although, significant quantities of coal fly ash and coal bottom ash are produced worldwide every year, less than 30 % of coal ash produced is reused. Coal ash is mainly reused in civil engineering applications such as road construction, embankments, construction materials ...

Towards sustainable coal industry: Turning coal bottom ash into wealth

Science of The Total Environment, 2022
Although the world is gradually moving towards renewable energy resources, the coal industry will continue to be a major energy supply sector in the foreseeable future. However, by-products such as coal fly ash (CFA), coal bottom ash (CBA), and boiler slag are generated during coal combustion, and have become a significant environmental concern.

Permeation Behaviour of Coal Bottom Ash Concretes

The Journal of Solid Waste Technology and Management, 2022
Low volume Coal Bottom Ash (CBA) was introduced as a substitute for Portland Cement (PC) and Fine Natural Aggregates (FNA) in concretes that were tested for permeation performance. Carbonation and chloride resistance was measured through accelerated carbonation tests and rapid chloride tests respectively while water penetration was evaluated through ...

Coal Bottom Ash (CBA)

2020
Coal bottom ash (CBA) is waste product that has been produced during the coal combustion for current generation. It is porous particle, angular and irregular in shape. Besides that, some of the particles were spherical and semi-spherical. There were also agglomerate particles and some CBA particles with interlocking characteristics compared than fine ...

Properties of Concrete Incorporating Coal Fly Ash and Coal Bottom Ash

Journal of The Institution of Engineers (India): Series A, 2019
Million loads of coal wastes are being generated everywhere across the globe in the form of fly ash and bottom ash. Utilization of such waste materials in concrete is an eco-friendly choice. Therefore, the objective of the current experimental investigation is to explore the effects of fly ash and bottom ash on the properties of concrete by replacing ...
