Abstract

In present work, an attempt has been made to improve the quality of bottom ash for utilization as a pozzolanic material. All samples were crushed and passed through 250 µm sieve to prepare grounded bottom ash. The physio-chemical, mineral and leaching characteristics of original and grounded bottom ash were studied. Results show that specific gravity and bulk density of all sample increases whereas porosity, water holding capacity and loss of ignition decreases after the grounding the bottom ash. Pozzolanic properties of bottom ash also improved after grounding the ash samples which helps to commercialize its utilization and reduce environmental impact.

印度火电厂底灰接地的综合表征
在目前的工作中,试图提高底灰的质量,使其成为一种火山灰材料。所有样品粉碎后通过250µm筛,得到磨碎的底灰。研究了原始底灰和磨碎底灰的理化、矿物和浸出特性。结果表明:底灰接地后,试样的比重和容重均有所增加,孔隙率、持水量和燃失量均有所降低;灰样磨后底灰的火山灰性质得到改善,有利于其商业化利用,减少对环境的影响。

期刊介绍: The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
