results concerning the mix design and fresh properties
of a high-performance fibre-reinforced fine-aggregate
concrete for printing concrete. This concrete has been
designed to be extruded through a nozzle to build
layer-by-layer structural components. The printing
process is a novel digitally controlled additive
manufacturing method which can build architectural
and structural components without formwork, unlike
conventional concrete construction methods. The
most critical fresh properties are shown to be extrudability
and buildability, which have mutual relationships
with workability and open time. These properties
are significantly influenced by the mix proportions and
the presence of superplasticiser, retarder, accelerator
and polypropylene fibres. An optimum mix is identified
and validated by the full-scale manufacture of a
bench component.
