Synthesizing Soil using By-products From Iron and Steel Industry
thesis
posted on 2020-01-14, 23:55 authored by SHASHIBHUSHAN BILIANGADIAn iron and steel industry generates around 150 to 200 kg of steel slag per tonne of steel
generated in basic oxygen furnace mostly using Linz-Donawitz (LD) process. In countries
like India and China, re-utilization of steel slag/LD slag for construction works and
production of cement is limited by virtue of its chemical characteristics such as presence of
free lime, free magnesium and phosphorous. Open dumping or storing of the LD slag is not an
environmentally sound or economically viable solution. The aim of this study is to find an
environmentally sustainable and techno-economically feasible technology for re-utilization of
LD slag. Synthesizing soil using LD slag is one such option which then could be used for
several applications such as reclamation of mines, landfills, landscaping, vegetation on
highway medians and public gardens.
