METHOD OF PLACING A FLOWABLE CONSTRUCTION MATERIAL
A method of placing a flowable construction material comprising a hydraulic cement for building structural components layer-by-layer, such as for 3D concrete printing, said method comprising:conveying the flowable construction material to a deposition head,placing the construction material through an outlet of the deposition head in order to form a layer of construction material,before placing the construction material, adding a thickening agent to the construction material so that the placed material has an increased yield stress before setting occurs when compared to the material during the conveying step,wherein successive layers of construction materials are placed on top of each other,wherein the thickening agent is added in the form of a colloidal dispersion of mineral particles dispersed in a liquid, the colloidal dispersion preferably having a pH value of ≥ 7.
