Suitability of leaching test methods for fly ash and slag: A review

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

Permeability and Leaching Characteristics of Fly Ash Liner Materials

Rigid-wall column tests are performed at a hydraulic gradient of 100 on 21 compacted mixture contai.ning a Class F fly ash, sand, benton.ite, and cement. Results indicate that combina1ions of the admixtures can lower the permeability of the fly ash by up to an order of magnitude. There appears to be an optimum percentage of fly ash that minimizes the permeability of fly ashsand mixtures. Specim...

Suppressing Heavy Metal Leaching through Ball Milling of Fly Ash

Ball milling is investigated as a method of reducing the leaching concentration (often termed stablilization) of heavy metals in municipal solid waste incineration (MSWI) fly ash. Three heavy metals (Cu, Cr, Pb) loose much of their solubility in leachate by treating fly ash in a planetary ball mill, in which collisions between balls and fly ash drive various physical processes, as well as chemi...
