The disclosure relates to a formwork device, in particular for arrangement between two bulkhead partitions of a battery mould, for manufacturing construction elements, in particular precast concrete elements, said formwork device comprising two formwork elements which each have a formwork front side for applying concrete and a formwork rear side, wherein the formwork elements are pivotably connected to one another at first end regions so that the formwork elements can be transferred from a vertical state into a horizontal state. The formwork device also comprises a spreading device for spreading apart second end regions of the formwork elements starting from the vertical state of the formwork elements, said second end regions being opposite the articulated connection. The disclosure also relates to: a battery mould comprising two bulkhead partitions and a formwork device according to the disclosure; a method for manufacturing a precast concrete element with the aid of the formwork device according to the disclosure; and a method for preparing the manufacture of a precast concrete element with the aid of the formwork device according to the disclosure.

A barrier wall is formed by rotating a mold to a horizontal orientation so that a rear wall of the mold is horizontally disposed and an encircling sidewall upstands from the rear wall, the floor and encircling sidewall at least partially bounding a compartment, an upper end of the encircling sidewall at least partially bounding a first access opening to the compartment. A first material is disposed into the compartment through the first access opening, at least a portion of the material being curable. A cover is placed over the first access opening to enclose the compartment. The mold is then rotated from the horizontal orientation to a vertical orientation. A portion of the sidewall is then moved to form a second access opening to the compartment. A second material is then dispensed into the compartment, at least a portion of the second material being curable.

A lightweight and strong tile constructed of a composition of cement, cellulous, perlite powder iron oxide and water is disclosed. The cellulous may include recycled paper products such as paper and cardboard that may be shredded. Excess water is removed by a vacuum and the composition is pressed to form a tile.

A method and manufacturing system for producing prefabricated parts of mineral-bound building materials, in particular for construction of buildings is disclosed. The manufacturing system includes at least one formwork table provided for casting the prefabricated parts of mineral-bound building materials as the essential component. The manufacturing system is mobile and it can be brought to the site of use of the prefabricated parts and in particular to the erection site of a building for manufacturing the prefabricated parts. Thus, this mobility allows transporting a complete small factory for manufacturing prefabricated parts of mineral-bound building materials to very different locations.
