Abstract: The present invention concerns a concrete strip, the strip comprising conventional concrete and a combined reinforcement of both post-tension steel strands and fibers, said post-tension steel strands—having a diameter ranging from 5 mm to 20 mm, —having a tensile strength higher than 1700 MPa, said fibers being either steel fibers and being present in a dosage ranging from 5 kg/m3 to 90 kg/m3 or being non-steel fibers and being present in a dosage ranging from 0.6 kg/m3 to 25 kg/m3, whereby the strip has a thickness, whereby further the length of the strip is according to the formula:length of the strip>30×strip thickness.

Abstract: A method includes the steps of (a) providing a flow of a flowable substance, the flow comprising bulk material and additional material; (b) determining the volume flow of the flow of the flowable substance at one or more detection points X along the flow of the flowable substance; (c) determining a signal caused by the additional material present in the flow of the flowable substance at one or more detection points Y along the flow of the flowable substance, the signal being proportional to the amount of the additional material present in the flow of the flowable substance passing the one or more detection points Y; and (d) converting the signal caused by the additional material present in the flow of the flowable substance into a signal per unit of volume of the flow of the flowable substance.

Abstract: The invention relates to a method to determine or monitor the amount or the distribution of additional material present in a flow of a flowable substance. The method comprises the steps of—providing a flow of a flowable substance, said flow comprising bulk material and additional material;—determining the volume flow of said flow of said flowable substance at one or more detection points X along said flow of said flowable substance;—determining a signal caused by said additional material present in said flow of said flowable substance at one or more detection points Y along said flow of said flowable substance, said signal being proportional to the amount of said additional material present in said flow of said flowable substance passing said one or more detection points Y;—converting said signal caused by said additional material present in said flow of said flowable substance in a signal per unit of volume of said flow of said flowable substance.

Abstract: Masonry (1) comprising layers (2) of bricks and mortar joints (3), whereby at least one mortar joint (3) is reinforced by a reinforcement strip (4), whereby said strip (4) comprises at least two straight, continuous, substantially parallel, steel reinforcement wires (5), which are welded or glued to each other by means of a steel wire connecting structure (6), characterized in that the wire connecting structure (6) is provided with protuberances (7) protruding from the plane comprising said at least two straight reinforcement wires (5) and forming spacing elements (7) which keep the at least two straight reinforcement wires (5) at a specific distance from the layer (2) of bricks below and/or the layer (2) of bricks above said reinforcement strip (4).

Abstract: The invention relates to an assembly of fibers (12) for concrete with RFID markers (10) or any other type of marker which can provide the information “I am here” and to a concrete or concrete structure (22) comprising fibers for reinforcement or any other purposes with RFID markers. The invention also relates to a method for determining the type and amount of fibers for the manufacturing of fiber concrete and to a method for determining the type, content and/or distribution of fibers within a fiber concrete with the help of the RFID markers.

Abstract: A casting method and apparatus according to which a molten material is poured into a space occupied by a foam-plastic pattern which is at least partially embedded in a granular material. The foam-plastic pattern when contacted by the molten material decomposes and disappears, while a gas is generated from the contact between the molten material and the foam-plastic pattern. From this generated gas, by way of a suitable structure situated in a mold together with the pattern and granular material, an elevated pressure is created, and the molten material fills the space initially occupied by the foam-plastic pattern in the presence of this elevated pressure which is greater than atmospheric pressure.
