[Object] Behavior of a flow of foam or foaming agent ejected to a gypsum slurry can be stabilized, and a relatively large amount of foam or foaming agent can be homogeneously or uniformly dispersed in the slurry.

[Solution] A mixer (10) has a mixing area (10a) for preparing gypsum slurry (3), a slurry delivery section (4) for delivering the slurry from the mixing area, and a feeding port (60) for feeding foam (M) or a foaming agent to the slurry in the mixing area and/or the slurry delivery section under pressure. The slurry having the foam mixed therein is supplied to a production line (1) for forming gypsum boards or gypsum-based boards. The feeding port is provided with a partition member (62,64,65) dividing an ejecting region (61,61). The ejecting region is divided into a plurality of openings (63), which simultaneously eject the foam or forming agent to the slurry.

A construction apparatus for forming modular construction components is disclosed. The construction apparatus comprises a first shell piece and a second shell piece that define an interior chamber defining a space for receiving a moldable material. The construction apparatus further comprises a separation device to move the first shell piece and the second shell piece from a closed configuration to an open configuration. The construction apparatus further comprises one or more cores within the interior chamber, one or more pins extending within the interior chamber, and one or more retaining plates for retaining the pins on the first shell piece. The interior chamber may be filled with the moldable material in the closed configuration and the moldable material may be cured. The construction apparatus may be shifted to the open configuration by the separation device and the pins and retaining plates may be used to extract the molded block from the first shell piece and/or second shell piece.

The present invention relates to a system for the production of thermal insulating, architectural and structural foam materials cast in molded volumes configured for a subsequent milling process, wherein molded foam volumes are cut into dimensional products or product components.

The present disclosure relates to a method for manufacturing a high-density heat storage molded body having a porous structure stable in a heat storage and release cycle, more particularly, to a method for manufacturing a molded body that is stable in a heat storage and release cycle, which includes steps of: preparing ceramic powder; mixing ceramic fibers with the ceramic powder; pressing and molding a mixed powder; and manufacturing the manufactured molded body in the form of a porous molded body by high-temperature heat treatment.

Methods and systems for creating a concrete fire feature with a mold include creating an aggregate mixture by combining a first mixture with an average grain size within a first range and a second mixture with an average grain size within a second range, the aggregate mixture comprising about 5% quartz or less. The methods and systems also include creating a dry mixture comprising an aggregate mixture proportion of the aggregate mixture and a water proportion of water, the water proportion comprising about 15% or less of the dry mixture. The dry mixture is pressurized to create a formed main body having an outer surface with a porosity of about 40% or less. The main body is cured outside the mold, and a fuel can is secured at least partially inside the hole.
