dc.description.abstract
This paper presents a novel concept of fibre reinforcement placement for digital fabrication with concrete, particularly suitable for 3D concrete printing, which aims at overcoming the limitations of adding the fibres to the concrete mix. In this process, the fibres are placed in-between layers, which allows aligning the fibres and grading their content according to the structural needs. The mechanical performance of this concept is investigated through a series of four-point bending tests in which the influence of different fibre contents and distributions, fibre types, sample geometries and time intervals between consecutive printing layers is studied. The crack kinematics were recorded using digital image correlation. Based on the crack kinematics, a refined inverse analysis is proposed to predict the direct tension behaviour. The results show that a deformation hardening structural behaviour might be reached at a relatively low fibre content (0.7 vol%) when the fibres are aligned. The performance is further increased when grading the fibre distribution over the height but keeping the overall fibre content constant. With an increasing number of fibres in-between the layers, however, a delamination failure caused by a concentration of anchorage stresses is observed, which limits the peak load and leads to severe softening behaviour.
