steel slag road

Like other metallurgical slags, steel slags exhibit a great potential to be used as aggregate in highway construction. 4. The purpose of this paper was to improve the management of this type of non-hazardous industrial waste. They are comparable to fluid magma from the earth’s core. The X-ray diffraction analysis detected the major mineral phases in WFBS as akermanite, gehlenite and monticellite that accounted for 91.4% of the total mineralogical phase composition. Enormous quantities of steel slag were deposited in yards, causing environmental pollution. The process for crushing and grading is repeated until. It is generated as a residue during the production of steel. JIS A 5015, 2018 Edition, December 20, 2018 - Iron and steel slag for road construction This Standard specifies requirements for the iron and steel slag intended for use in a base course mixture or hot laid asphalt mix for road construction (hereafter referred to as iron and steel slag). Presently, the rate of utilization of steel slag in Malaysia is rather too low compared to some advanced countries. Steel slag is a byproduct obtained from steel industry. 1.
