Abstract:
Electric arc furnace dust (EAFD) is produced by Saudi Iron & Steel Company – HADEED factory in Jubail as a by-product during steel making process in the electric arc furnace at the rate of more than 20,000 tons per year. The dust is classified by international standards as an environmental hazard; therefore, finding a safe-way to dispose of the dust contributes to cleaner environment.
The use of byproducts from Sabic’s Steel Industry (Hadeed) factory in concrete was studied in a two-phase research project between SABIC and the College of Engineering at King Saud University. Phase 1 lasted for 19 months from 1/6/1413 to 1/1/1415H and Phase 2 lasted for 18 months from 1/6/1415 to 1/12/1416H. The results from these investigations revealed that the BHD could be used as an effective set retarder in concrete with enhanced concrete properties. Two patents on the use of EAFD in concrete were granted, one by the American Patent Office in 1996G and the other by the European Patent Office in 2000.
