Claim:
1. A method recycling Electric Arc Furnace Dust (EAFD) as stabilized concrete, comprising the steps of: placing a premeasured amount of aggregate into a mixer; mixing absorption water with the aggregate; adding cement and sufficient water to form a water-binder ratio of 0.52 by weight to the mixer; adding 3% EAFD by weight of the cement and sufficient water to the mixer to maintain the water-binder ratio of 0.52; mixing the EAFD stabilizer, water, aggregate, and cement for about 5 minutes; allowing the EAFD and cement to stabilize for a period between about 22 hours to about 26 hours to stabilize the mixture; and casting the stabilized mixture.
