Abstract (en)
The invention relates to the construction sector, to apparatus for preparation of cellular concrete, and introduces a separation between the production stages, which are performed by two distinct but complementary apparatus: one for production of the water/cement mixture, the other for foam production, foam mixing with the grout and laying. The division of the production procedures by separating the apparatus enables work to be done in a continuous mode, guaranteeing rapidity and quality. By positioning the station for foam production and pumping at the laying level, structural shrinkage caused by collapsing of air cells after pumping, typical in the prior art, is prevented. The invention remotely pumps only the grout, whereas the product integrated with the foam is produced and laid by the mobile second apparatus, which is transported by the operatives as they move up through the building's floors, meaning that the operatives can work in high buildings or in positions that are remote from the locus of production of the grout, without there being any need for further intermediate pumping stations.
