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 forming system and methods that can more efficiently, safely, and economically produce pre-cast modular blocks having desired shapes and surfaces, such as those having reverse tapered shapes. The forming system and methods disclosed herein allow for quick, easy, and efficient demolding and reinstalling of inserts for the production of reverse tapered pre-cast modular blocks.

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 method for exchanging molds in a concrete products forming machine (CPM) comprises moving a first mold cassette assembly along a linear path to a mold receiving position adjacent to a concrete products forming machine. The first mold is then moved out of the CPM along a mold-transfer path perpendicular to the linear path of the first mold cassette assembly. The first mold is then mounted within the first mold cassette assembly which then moves along the linear path out of the mold-receiving position. The second mold cassette assembly, and pre-mounted second mold, are then moved along the linear path to the mold-extracting position. The second mold is then demounted from the second mold cassette assembly and moved along the mold-transfer path to the concrete products forming machine to effect a mold change within the CPM.

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.
