Extrusion and Subsequent Transformation of Textile‐Reinforced Mortar Components—Requirements on the Textile, Mortar and Process Parameters with a Laboratory Mortar Extruder (LabMorTex)

Abstract

To produce defect‐free extruded and shaped components, the forming behaviour of extruded fibre‐reinforced mortar mixtures, impregnated textiles and extruded textile‐reinforced mortar (TRM) was investigated. The TRM test specimens were formed longitudinally and transversely using specially developed forming setups. Regardless of the selected fibre content ranging between 0 and 0.5 Vol.‐%, defect‐free longitudinal forming of the mortar is possible up to a bending radius of 5 cm and transversely up to a bending radius of approx. 6 cm. For the extruded TRM specimens, longitudinal bending radii of up to 10 cm were achieved. The results represent the basis for the construction of new formwork‐free extruded and subsequently shaped textile‐reinforced concrete components.
