Abstract:
As the supply of conventional supplementary cementitious materials (SCMs) continues to fall behind concrete industry’s demand, new sources must be identified and evaluated to allow production of high-quality and durable concrete. This session reports on the latest research related to the use of harvested fly ash (HFA) and ground bottom ash (GBA) as concrete SCMs. The presentations will include studies on the chemical and physical characteristics of these ashes, their pozzolanic reactivity, and their performance in concrete in terms of their impact on fresh, mechanical, and durability properties of concrete mixtures. The audience will become familiar with this potentially valuable new SCM source.
