Solidification/Stabilization of MSWI Fly Ash Using a Novel Metallurgical Slag-Based Cementitious Material

An Experimental Study on Utilization of Slag and Fly Ash as an Alternative Cementitious Binder

This study investigates the utilization of slag and fly ash (FA) as alternative cementitious binder. Combination of 60% slag and 40% FA was used as new binder. In addition, for activation of slag and FA, sodium hydroxide and calcium hydroxide was used as a chemical activator by 5% weight of the binder, separately. Water to binder and sand to binder ratios was kept 0.55 and 3 in mortar preparati...

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

Initial studies of the recovery of Cu from MSWI fly ash leachates using solvent extraction.

Large volumes of ash from combustion of municipal solid waste are produced and most of it is landfilled. As this type of ash contains significant amounts of metal compounds the landfilling strategy is not optimal when considered from a resource conservation perspective. A better situation would be created if metals were recovered from the ash. In the present study leaching and solvent extractio...

A Case Study of the Microwave Sintering for the Stabilization of Mswi Fly Ash

Municipal solid waste incineration fly ash is generated in a significant amount; it is classified as hazardous waste in Taiwan. In order to reduce the volume of treated fly ash, a sintering technology can be considered. However, a traditional sintering consumes too much energy because of the limit of heat transfer. Hence, a microwave process which can provide quick, uniform, and selective heati...
