  • Patent number: 12226930
    Abstract: A concrete construction (100) made by 3D concrete printing that contains: two or more layers (102, 106) of cementitious material extruded one above the other, and at least one elongated steel element (104) reinforcing at least one of the layers (102, 106). The elongated steel element (104) has an elastic and plastic elongation at break that exceeds 4%. The high elongation of the elongated steel element gives an increased ductility to the concrete structure (100).

  • Publication number: 20240207981
    Abstract: A deposition wire of the powder-in-tube type comprises a hollow tubular portion of titanium and a core portion filling the tubular portion. The core portion occupies between (30) volume % and (80) volume % of the deposition wire. The core portion comprises compacted elongated powders of titanium and possibly also comprises other compacted powders selected from the group consisting of aluminium, vanadium, aluminium-vanadium, chromium, molybdenum, boron, niobium, tantalum, nickel, zirconium, silicon, copper, tin, iron and palladium. Due to the high volume of the core portion, the process of making the wire is less complex.

  • Publication number: 20230094390
    Abstract: A concrete construction made by 3D concrete printing having two or more layers of cementitious material extruded one above the other, and a reinforcing structure reinforcing the two or more layers. The reinforcing structure has at least two flexible longitudinal elongated steel elements running in lengthwise direction, and one or more flexible transverse steel elements forming an angle with the lengthwise direction so that these flexible transverse steel elements are present in the two or more layers. The structure also has a positioning element for positioning the at least two flexible longitudinal elongated elements and the flexible transverse steel elements, a polymer coating or yarns making stitches. The polymer coating or the stitches are applied on the at least two flexible longitudinal elongated steel elements, on the flexible transverse steel elements and on the positioning element thereby making a bond.

  • Publication number: 20230061766
    Abstract: A concrete construction (100) made by 3D concrete printing that contains: two or more layers (102, 106) of cementitious material extruded one above the other, and at least one elongated steel element (104, 108) reinforcing at least one of the two or more layers. The elongated steel element (104, 108) is provided with a first crimp. Due to the crimp, a good anchorage in concrete is obtained and the anchorage force is predictable, since the standard deviation of the anchorage force is very small. The elongated steel element can be a single steel wire with a diameter D, the amplitude of the crimp ranges from 1.05×D to 5.0×D. The elongated steel element can also be a steel with steel filaments having a maximum diameter d. The amplitude of the crimp ranges from 1.05×d to 5.0×d.
