Document Type and Number:
Japanese Patent JPH08502713
Kind Code:
A
Abstract:
A method and a mixture for chemically stabilizing electric arc furnace dust (EAFD) by entrapping the metals inherent in EAFD within a cementitiously hardened product from the mixture. The method includes using the pozzolanic characteristics of EAFD and forming a mixture of EAFD with sufficient water and lime, as necessary, and then allowing the mixture to react to form a cementitiously hardened product. The hardened product has acceptable leachate concentrations, permeability characteristics and unconfined compressive strength.
