The disclosure relates to formwork for producing a concrete element, in particular a wall element or ceiling element, having an opening, in particular a window opening or door opening, the formwork comprising: a formwork panel; opening formwork, which has a frame element for delimiting a portion of the opening, a support bracket for supporting the frame element, and a mounting element for mounting the support bracket; a formwork-stripping device for transferring the opening formwork from a formwork position for the formation of the opening into a formwork-stripping position for the release of the concrete element, wherein the formwork-stripping device has a sliding and tilting mechanism for sliding the frame element in a direction parallel to the formwork panel and for tilting the frame element about a pivot axis running substantially parallel to the formwork panel.

A module for a paving or building system includes at least one block of concrete and a sheet, e.g., sheet metal, having a surface area abutting the block or blocks. The sheet includes multiple openings and one or more flaps of material from one or more from the openings may be bent or otherwise shaped to extend into a concrete block and anchor the sheet to the concrete block.

A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.

Mould for casting of thin samples made of cement-based materials, for a maximum of 10 small samples (10×10×2 mm or ⅜×⅜× 1/16 inch), consists of a solid stainless steel base plate, stainless steel upper frame-plates and thin plastic foil. The stainless steel frame plates of various lengths are assembled on the base plate and fastened with screws to form a frame with 10 free spaces (‘cells’) into which the concrete/cementitious material is poured. The thickness (2 mm or 1/16 inch) of the thin frame plates determines the thickness of the cast samples. Plastic transparent foil is placed over the surface of the base plate for easier sample removal. The advantages of the mould are: possibility of assembling and disassembling of all mould parts and hence safe sample removal after 24 hours, multiple usage as well as easy maintenance and cleaning.
