Effects and Mechanisms of Al Powder, Soybean Oil, and Expanded Polystyrene on Performances of Novel Foamed Geopolymers Utilizing Multiple Solid Wastes

Abstract

AbstractTo address the challenges of high energy demands of cement and high costs of alkali activated materials in the preparation of foam concrete, this study innovatively uses all solid waste to prepare foamed geopolymers (FGs). A systematic ...Practical ApplicationsThis study presents a novel insulation material made of all solid waste, including red mud, carbide slag, ground granulated blast-furnace slag, and municipal solid waste and incineration fly ash (FA). These difficult-to-recycle ...
