100% cement as binder. It should also be mentioned that in most cases during printing, it was observed that fly ash mixtures showed reduced values and higher loss rate of workability with time compared to other mixtures. However, lower cost and volume stability of hardened concrete are expected to be the advantages of using fly ash or ladle furnace slag in concrete for 3D printing.
