Abstract: The container comprises a pressed dry mortar molded body, and pressing agents. The container is obtained from a manageable transport container, and is fully filled with mineral building material in form of prefabricated mineral and with water and optionally an additive to make a premixed dry mortar as packaged goods. The transport container of a piping bag is water tightly and air tightly locked with a hermetical closure device (3). The packaged goods consist of a blasting unit reacting with the water containing press- or construction granulate grains (5) of a premixed dry mixture. The container comprises a pressed dry mortar molded body, and pressing agents. The container is obtained from a manageable transport container, and is fully filled with mineral building material in form of prefabricated mineral and with water and optionally an additive to make a premixed dry mortar as packaged goods. The transport container of a piping bag is water tightly and air tightly locked with a hermetical closure device (3). The packaged goods consist of a blasting unit reacting with the water containing press- or construction granulate grains (5) of a premixed dry mixture that forms a gusset space (6) into the piping bag. The piping bag of the closure device comprises an oppositely tapered outlet area for its discharge, and consists of transparent plastic film. The container has a volume of 3.3-20 liter. A gusset space volume between the pressed grains of premixed dry mortar mixture is 20-35 vol.% of the total volume of the container. Grain size of a premixed dry mortar pellet into the hermetically sealed container is 12-32 mm. The piping bag in its outlet area of a spatial form: comprises a cornet; and has a cone-, a wedge- or pyramid-shape. The outlet area of the piping bag comprises an opening covered with a detachable strip such as adhesive strip, a closable sleeve or a closable nozzle. The hermetic closure device is folded from one another, and is felled or rolled on top of each other. A filler hole area of the piping bag is formed with a glued or welded piping bag wall part. The dry mortar molded body comprises: a hydraulic binder such as cement, lime, gypsum, granulated blast furnace slag and/or puzzolanes in a range of 15-35 wt.%; mineral aggregates such as rock sand and/or rock flour including quartz sand, quartz flour, limestone flour, limestone sand and/or other aggregates in the range of 60-80 wt.%; a disintegrant; a pressing agent; and optionally an additive such as setting regulation agent, flow agents, air entraining agent, water retention agent, and/or redispersible powder in the range 0.05-1 wt.%. The molded body contains a mineral, porous, relatively tender, dry lightweight aggregate granules from cysteamine granules such as aerated concrete, foam concrete, expanded perlite, expanded vermiculite, pumice and/or expanded clay with residual moisture of a maximum of 2-30 wt.%. The pressing agent has a particle size of 2 mm. Additional pressing agents are present in the form of layer silicate such as lime and/or clay mineral such as bentonite in the range of 0.2-5 wt.%, and/or in the form of a stearate such as calcium- and/or magnesium stearate in the range of 0.2-3 wt.%. The molded body as a disintegrant contains quicklime and/or burnt dolomite, soft quicklime with t 6 0values of less than 1 minute in the range of 0.5-5 wt.%. The disintegrant contains fine lime (less than 5 wt.%) having particle size of greater than 0.09 mm, or granular limestone (less than 10 wt.%) having a particle size of 0.5 mm. The premixed dry mortar molded body contains a substance such as a metal powder including aluminum powder in the range of 0.05-0.5 wt.% forming with water in an alkaline environment gas. An independent claim is included for a process for producing a fresh mortar on a structural body using a container.
