Described is an insulating layer-forming composition that comprises a binding agent, based on addition-crosslinking polyorganosiloxanes. The inventive composition having a rate of expansion that is relatively high allows coatings having the layer thickness required for the respective period of fire resistance to be applied in a simple and fast manner, while at the same time the layer thickness is reduced to a minimum and yet a high insulating effect can be achieved. The composition of the invention is particularly suitable for fire protection, in particular, as a coating of metallic and non-metallic substrates, for example, steel construction elements, such as columns, beams, truss members, in order to increase the period of fire resistance.

Described is an insulating layer-forming composition, which contains a binder based on epoxy-thiol. The inventive composition, its rate of expansion ratio is relatively high, allows coatings having the layer thickness, required for the respective period of fire resistance, to be applied in a simple and fast manner, while at the same time the layer thickness is reduced to a minimum and yet a high insulating effect can be achieved. The composition of the invention is particularly suitable for fire protection, in particular as a coating of metallic and non-metallic substrates, such as steel components, like columns, beams, trusses, in order to increase the period of fire resistance.


A method for producing molded foam parts for construction and civil engineering has the following steps: Inserting a packaging sleeve of the molded foam part to be produced into a molding tool, filling a flowable foaming material into the packaging sleeve within molding tool, filling the cavity defined by molding tool and packaging sleeve with foam, and removing the molded foam part produced, together with its packaging sleeve.


A method for producing a green compact from a powdered or granular material is disclosed. An embodiment of the method includes moving a fill shoe, which is filled with powdered or granular material, by an adjusting device from a first park position to a first end position. The fill shoe is moved from the first end position to a second end position over a construction chamber and the construction chamber is filled with the powdered or granular material in the fill shoe in a layer. The fill shoe is moved from the second end position to a second park position after filling the construction chamber with the layer, where the second park position is different from the first park position.


The invention relates to a device for passing pipes or cables through an opening in a building. Said device comprises a sleeve-like housing that has an axial passage channel that is open at its opposite ends; bristles that are mounted on the walls of the passage channel in such a way that they are opposite each other and that are extended inwards in such a way that they mesh with one another in order to close the passage channel; and flexible strips of material that are mounted in the passage channel and that are coated with an intumescent material.


A through-penetration device has a molded body consisting essentially of an intumescent foam material and having at least one penetration opening for one line. An outer contour of the molded body has protrusions extending radially outward for anchoring within a cast building component, which protrusions form undercuts in building component as the building component is being cast. In addition, a mounting plate that can be axially pushed onto the through-penetration device, sealing the penetration openings, is provided. As the through-penetration device is produced, a liquid coating material is applied to a surface of a foaming mold, and then a foam mass containing a predetermined percentage of intumescent material is introduced into the foaming mold. After a foaming process, the coating material forms a water-impermeable skin on the foamed molded body.


A resin mixture is described, comprising at least one compound that can be radically polymerized, at least one reactive diluent selected from 1,3-dicarbonyl compounds, and at least one polymerization inhibitor, selected from stable N-oxyl-radicals or 4-hydroxy-3,5-di-tert-butyl toluene, with the molar ratio of at least one 1,3-dicarbonyl compound and the polymerization inhibitor ranging from 30:1 to 150:1, a reaction resin mortar comprising said resin mixture, a two-component or multi-component system, as well as the use for construction purposes, particularly for the chemical fastening in mineral undergrounds.


A reaction resin mortar comprising a resin mixture is described, that contains at least one radically polymerizable compound, at least one reactive diluent and at least one inhibitor, whereby the viscosity of the resin mixture is set to a particular value, a two-component or multi-component mortar system and the use thereof for construction purposes, in particular for chemical anchoring in mineral substrates.
