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 our 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.
