A scalable and sustainable process for transforming incineration bottom ash into useable aggregates

Abstract

Herein disclosed is an aggregate comprising a cement comprising ordinary Portland cement, a ground granulated blast-furnace slag, and bottom ash, wherein the cement is hydrated in the presence of the ground granulated blast-furnace slag to have a calcium silicate hydrate or derivative thereof formed which encapsulate the bottom ash. A method of producing the aggregate is disclosed herein also, the method comprising mixing the cement and the ground granulated blast-furnace slag with the bottom ash in the presence of water to form pre-coated bottom ash, and granulating the pre-coated bottom ash.
