Title: Fly Ash Geopolymer Pervious Concrete

Author(s): Gang Xu and Xianming Shi

Abstract:
A geopolymer pervious concrete mixture was developed with alkali activation of fly ash under ambient conditions. A novel nanomaterial, graphene oxide, was used to facilitate the polymerization of fly ash hydration products. The mixture was then exposed to cyclic freezing-and-thawing and salt weathering and the transverse resonance frequency was used to monitor changes induced by these exposures.
