Characterization of Limestone Aggregates for Iron-Steel Industry

Abstract

Limestone is a basic industrial raw material. It is consumed by 84% in chemical industry, 12% in refractory
and road construction and 4% in civil engineering, agricultural applications and iron steel industry and substantial
quantity as lime. Limestone as a source of lime should have some specific physical, chemical, mechanical and thermal
properties. Furthermore, technological processes for high quality lime production are also very important. In this
investigation, chemical composition, physical properties (bulk density, apparent porosity, water absorption rate),
mechanical properties (Schmidt strength and Los Angeles Abrassive strength) and thermogravimetric properties (TG
DTA) of limestone samples were determined. The tests were carried out to determine the characteristic properties of
limestone for high quality lime production suitable for iron-steel making industry.
