Effect of incinerator fly ash in cement mortar toward compressive strength and leaching characteristic

Today, incinerator used to bum municipal solid waste widely in developed countries including Malaysia. MWS fly ash produced from incinerator will donated a percentage of the material is disposed in landfill. Due to the increasing costs of landfill and the current interest in sustainable development,...
