ACI publishes Graphene Oxide-Modified Pervious Concrete with Fly Ash as Sole Binder

The American Concrete Institute (ACI) has released a paper called Graphene Oxide-Modified Pervious Concrete with Fly Ash as Sole Binder.

The document, written by Gang Xu and Xianming Shi, covers an environmentally friendly pervious concrete which was developed using fly ash as the sole binder modified by graphene oxide (GO).

ACI says the density, void ratio, mechanical strength, Young’s modulus, infiltration rate, deicer salt scaling, and degradation resistance of this pervious concrete were measured against three control groups.

“The test results indicated that the addition of 0.02% GO (by weight of fly ash) significantly increased compressive strength, split tensile strength, Young’s modulus, deicer salt scaling resistance, and degradation resistance of the fly ash pervious concrete”, ACI adds.

Overall, the innovative fly ash pervious concrete showed a comparable performance to Portland cement pervious concrete.

According to ACI: “A microscopic investigation using an electron microprobe was also conducted to obtain more insights on the effects of GO and chemical activators on the fly ash pervious concrete.”
