Abstract
Official abstract text for this publication.
The EAFD stabilizer for returned concrete and mixer drum wash water includes various methods of using EAFD as a stabilizer in making concrete. The potentially hazardous stockpile of EAFD can be used in practical construction, which has a positive impact on the environment. A certain amount of EAFD is added to cement being mixed or to wash water and acts as a stabilizer, the wash water being used to make a cement mixture. This resultant EAFD stabilized concrete mixture stabilizes overnight.
First claim
Opening claim text (preview).
We 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. 2. The method of recycling Electric Arc Furnace Dust (EAFD) as stabilized concrete of claim 1 , further comprising the step of maintaining a temperature of about 20° C.
