Description

Description

As the supply of conventional supplementary cementitious materials (SCMs) continue 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 ground bottom ash as a concrete SCM. These include studies on the chemical and physical characteristics of ground bottom ash, its pozzolanic reactivity, and its performance in concrete in terms of its impact on fresh, mechanical, and durability properties of concrete mixtures. The audience will become familiar with this potentially valuable new SCM source.
