Utilization of Bottom Ash for Sintered Artificial Aggregate

Abstract:

At present high temperature fly ashes are already quite widely used as a secondary raw material in building materials. Fly ashes are usually able to fully replace classical materials. FBC ashes also gradually finding their place for example in production of autoclaved aerated concrete, in binders or solidification of hazardous waste. However, the coarser types of energy by-products are relatively difficult to use. Therefore, this part of the work focused on the study of usability of bottom ashes for artificial sintered aggregates. The article will focus on results of laboratory firing in muffle furnace, dedicated to testing of maximum bottom ash content in the mixture with the fly ash and special type of clay.
