Abstract
A method for manufacturing concrete bodies or forms containing electric arc furnace dust in an amount of up to about 4% at elevated temperatures to provide concrete bodies is disclosed. The concrete bodies have improved compressive strength and slump retention capability. The method for producing the bodies includes the steps of providing pre-selected amounts of electric arc furnace dust, water, cement and aggregate. The electric arc furnace dust is mixed with water and then added to the cement and aggregate and mixed together at a temperature of about 32° C. and 45° C. to form a hot mixture. The hot mixture is added to a mold and cast at an elevated temperature to form a body with improved strength and slump retention characteristics.
