Project description

Fly ash, as a main by-product of coal-fired power plant, is one of the most used supplementary cementitious materials (SCMs) in concrete. Research is much needed to greatly advance understanding in the use of nanotechnology for high-volume fly ash concrete (HVFAC), especially when such concrete is intended for pavement applications. The primary objective of this project is to develop a viable nanotechnology approach to treat coal fly ashes based on their as-received characteristics before their use in sustainable concrete pavement. The use of nanotechnology to address weak interfaces in such sustainable concrete is a highly innovative approach.
