Behavior of Geopolymer Concrete Confined by Circular Hoops

MATEC Web of Conferences, 2018
This paper discusses the behavior of geopolymer concrete subjected to passive confinement under compression loads. The confinement is induced by the use of lateral hoops, assembled from un-deformed reinforcing bars.
