The aim of this paper is to characterize the influence of wood sawdust and fibers on the extrusion behavior of a material with a cement matrix at various substitution levels of sand by wood aggregate. A study of the slump of extruded mixtures highlights the fluidity of these replacement mixtures. For the case of sawdust, the extrusion force recorded during testing indicates that the mixtures serve to reduce the necessary extrusion force. This extrusion behavior is not the same in the case of mortar fibers.
