  • Publication number: 20210319377
    Abstract: The subject matter of the present application relates to a test method for determining the risk potential of an alkali-silica reaction in mineral construction materials such as concrete. The test method may be characterized by the steps of: a) examining (220) a sample (12) by means of Raman spectroscopy for providing a structural characterization (230) of the sample (12), b) comparing (240) the examination result to values (250) stored in a database, and c) using (260) the result of the comparison (240) for ascertaining (270) a risk potential for the concrete for an alkali-silica reaction.

  • Publication number: 20210069724
    Abstract: A fragmentation system for electrodynamic fragmentation of material contains a feed and an outlet for transporting material along a transport path in a transport direction. At least one high-voltage pulse source is provided, each of the high-voltage pulse sources contains at least one first electrode and at least one second electrode for generating a high-voltage discharge in a discharge chamber. The transport path has a fractionation section, and the fractionation section extends through the discharge chamber. A selection device for selectively extracting the material on the transport path is provided in order to channel material and/or fragments of the material having a diameter smaller than a minimum diameter past at least one portion of one of the fractionation sections.

  • Patent number: 9603683
    Abstract: A method for producing a dental restoration (D) by CAD casting is described, said method comprising the steps of a) recording three-dimensional, digital data of the dentition or of a part of the dentition of a patient, b) creating a virtual dental restoration (VD) using the recorded three-dimensional, digital data, wherein the virtual dental restoration (VD) is expanded in relation to the dental restoration (D) to be produced, c) preparing a model (M) using the created virtual dental restoration, such that the model (M) is expanded in relation to the dental restoration (D) to be produced, d) embedding the model (M) in an embedding compound (EM), e) hardening the embedding compound (EM) and removing the model (M), such that a casting mold is obtained, f) filling the casting mold, preferably by pouring, with a casting material (GM) and cooling the casting material (GM), such that the dental restoration (D) is obtained, and optionally the further steps of g) working the dental restoration (D), and h) veneering t
