Abstract: The present disclosure relates generally to methods of analysing and manufacturing gypsum panels, for example, suitable for use as building surface products. The present disclosure relates more particularly to a method of forming a gypsum panel. The method includes forming a porous slurry layer on a receiving surface using a plurality of operating parameters, and allowing the porous slurry layer to set to form a gypsum core of a gypsum panel. The panel is then cut to form a cut surface that extends through the gypsum core, and an image of a region of the cut surface is captured. The image is analysed to identify bubbles intersecting the cut surface. A measure of bubble contact in the gypsum core is then calculated from the identified bubbles in the image. Based on the measure of bubble contact, an operating parameter used for forming the porous slurry layer is modified.

Abstract: Disclosed is a measurement device for a vibration device of a concrete-block production plant. The vibration device has a vibrating table and impact strips arranged parallel to each other and parallel to the ground with relation to their longitudinal axes. The measurement device comprises at least one measurement unit for distance. The measurement unit is arranged above the vibrating table and the impact strips, wherein the measurement unit can be guided orthogonally to the impact strips and parallel to the ground using a guide unit. During the guiding process, the measurement unit operates at predefined measuring positions and/or positions determined during the guiding process via the impact strips and the vibrating table, using the measurement unit, the vertical distances from the top sides of the impact strips and/or the vibrating table to reference positions, which result from the heights of the measurement unit at the respective measuring positions, can be determined.

Abstract: A concrete compaction device includes a vibrator housing for immersion in flowable concrete, and an unbalance exciter which is driven by an electric motor and which is arranged in the vibrator housing. A current detection device detects the electric current absorbed by the electric motor. Ann evaluation device determines an operating state of the concrete compaction device based on the electric current that is currently detected. The operating state is selected from the group consisting of: positioning of the vibrator housing in the air, immersion of the vibrator housing in the concrete, performance of a compaction process with the vibrator housing immersed in the concrete, and emersion of the vibrator housing from the concrete. The evaluation device is configured to recognize all of these operating states.
