Towards earthen structures as artefacts ofresilience
Comparable with rammed-earth construction, though free of rigid forms, it’s possible to 3D-print a 3m earthen wall in one day. Successful 3D-printing with earth + biomaterials is dependent on the sophisticated calibration of inputs which influence the behaviour and ‘green-strength’ of the clay- based material.
Pozzolanic binders (additives) made available as by-products of the sustainable energy sector–such as biochar or bottom ash from Waste-to-Energy processing, or as biopolymer binders, such as alginate salts derived from seaweed–determine the extruded material’s green-strength during printing and when having cured, desirable high compressive strength with minimal shrinkage.
