“…Coal analysis results obtained in line with research conducted by Tiwari et al [6] using EDXRF which resulted in the relative abundance of the elements in the coal were Si> Al> Fe> Ca> Mg> K> Na> Sr> V> Zn> Mn> Cr> Cu> Pb> Ni> Co> Al> Cd, where the concentration of Al found was most abundantly after Si which ranges from 3.21% and Cd found in coal was the least that was only about 0.37 mg/kg. Research conducted by Sutcu and Karagiyit [14] stated that the main elements such as Al and Fe from the coal sample were mostly associated with silicates and carbonate minerals.…”

“…This is in contrast to the results of research conducted by Tiwari et al [6] in which the concentration of the element Al in the bottom ash and fly ash greater than the elements Fe, and Al elements found to be higher in the bottom ash compared with fly ash. This indicates that the element content in the combustion products (bottom ash and fly ash) from the power plant will have different characteristics from other power plants in addition to the type and origin of coal.…”

“…The sample forms could be solid (granular, massive), paste as well as liquid, nondestructive, as well as an easy way of calibrating. In spite of the advantages mentioned above, XRF technique has a disadvantage in performance, that is, it is influenced by sample matrix and standard, and also needs the different exitation sources (radio isotope) for some elements [6]. The different techniques were used in characterizing coals, bottom ash and fly ash to give an evaluation when one method with others have lacking in determining an element composition.…”

“…Instead of dumping, the physical and chemical properties of CBA shows that it could be used as a possible applications including as cement replacement, ceramic products and construction materials [1][2][3]. Previous researchers have proved the existence of silica as a major compound and heavy metal impurities in coal bottom ash [4][5] and therefore, there is a possibility to extract silica from coal bottom ash and at the same time reducing the heavy metal element in coal bottom ash.…”

Abstract. Coal ash is the residue that is produced during coal combustion for instance fly ash, bottom ash or boiler slag which was primarily produced from the combustion of coal. With growth in coal burning power station, huge amount of coal bottom ash (CBA) considered as hazardous material which are normally disposed in an on-site disposal system without any commercialization purpose. Previous researchers have studied the extraction of silica from agricultural wastes such as palm ash and rice husk ash (RHA) and CBA by using leaching treatment method. In this study, the weaker acid, citric acid solution was used to replace the strong acid in leaching treatment process. Result showed that the heavy metal content such as Copper (Cu), Zinc (Zn) and Lead (Pb) can be decrease. Meanwhile the silica can be extracted up to 44% from coal bottom ash using citric acid leaching treatment under the optimum reaction time of 60 minutes with solution temperature of 60 0 C and concentration of citric acid more than 2%.

A Comprehensive Review on the Properties of Coal Bottom Ash in Concrete as Sound Absorption Material

Abstract. The government is currently implementing policies to increase the usage of coal as fuel for electricity generation. At the same time, the dependency on gas will be reduced. In addition, coal power plants in Malaysia produce large amounts of industrial waste such as bottom ash which is collected in impoundment ponds (ash pond). However, millions of tons of coal ash (bottom ash) waste are collected in ponds near power plant stations. Since bottom ash has been classified as hazardous material that threatens the health and safety of human life, an innovative and sustainable solution has been introduced to reuse or recycle industrial waste such as coal bottom ash in concrete mixtures to create a greener and more sustainable world. Bottom ash has the potential to be used as concrete material to replace fine aggregates, coarse aggregates or both. Hence, this paper provides an overview of previous research which used bottom ash as fine aggregate replacement in conventional concrete. The workability, compressive strength, flexural strength, and sound absorption of bottom ash in concrete are reviewed.
